VW Jetta Electrical Problems



  • jeffyscottjeffyscott Posts: 3,855
    Ah, I see, only $250, that's only a little more than the scrap value, then. Does the key turn? If it does it must be the correct key, right?

    I wouldn't think it is an alarm issue. I don't think that would result in the steering wheel not unlocking, I could be wrong, though.
  • Dan Give this a try. Observe which way the tires are facing. If they are turned left or right, give steering wheel a hugh FORCEFUL TUG towards the way the tires are turned and hold the steering in that position while attempting to turn key. Hopefully this will work. Goodluck :)
  • : The problem that i am having is the car not starting ? What gets me is the car ran fine in the morning but when I went to drive it in the afternoon it would not crank You turn the key on and the ASL light comes on then immediately goes off and a relay clicks in the gear shift console. The gear indicator on the instrument cluster starts to flicker on and off and when I turn the key to start it ... absolutely nothing happens. battery also drains and gets hot after a few tries...plz help
  • just wanted to know if you ever found a solution to your electical problems you were having with your jetta i seem to have the same problem. thanks
  • I never officially found the answer. I replaced the alternator and the battery. It appears that the last 2 batteries I got from Sears were not a perfect match for the car. This time I replaced it with a Bosch battery for Pep Boys and have not had a problem since I did. If the problem returns I will be posting that here as well. All looks good.
  • just wanted to thank you for the feedback replaced the battery and it started right up hopefully that was the problem thanks again...:)
  • i have a 1998 vw jetta and for some reason the ignition coil burns out, than i put a new ignition coil and the new one burnsout too, i am tired of changing the ignition coils, what is the reason that ignition coil burns out??,
  • you are prob grounding out somehwere
  • has anyone experienced this?? (Jetta/yr 2000, 2.0 ltr, manual). the other day when i re-started my car after a brief drive/visit to a mall, the interior chime would not stop ringing even after putting on my seat belt. the interior lights would not go out (front centre lights + rear door lights etc). i had to manual turn them off, even though they should all fade out after a few seconds. Eventually, the interior chime did end, but only after about 2 minutes. also, if i now turn on my headlights, the headlight warning buzzer will sound and wont go off even while the car is running. it's torture driving around with your headlights on with this annoying buzzer. add to this, my key wont manually lock all the door locks as it used to (insert key in driver side door, turn key to lock all doors). also, my driver side lower door light wont go out.. it remains on no matter what. all this strange electical behaviour appeared at once. any ideas?? im stumped.

    02 jetta 1.8t tiptronic automatic the displays for clock, gears and milage are scrambeled??
  • I have a 2001 Jetta 1.8T. About a year and a half ago I went through several very costly repairs and finally got my car back after a couple of months I began having a problem with the battery dying. I finally gave up on it and it sat for a year. I am now trying once again to get it up and running and the garage is having trouble diagnosing the problem. They have replaced the battery, but after 3-4 day the battery is completely dead. They have checked the output and it doesn't seem to have a power leak but it still ends up dying. I know that if I bring it to another garage they'll end up changing the battery again and I'll end up in the same place and this garage is willing to work on solving the problem (without additional cost) so I'm curious if anybody has any idea what it could be...any help would be appreciated.

  • I have a 1997 jetta GT. It will not start. I bought the car and the person I bought it from said all it needs is a tranny. So I had another jetta and I switched the trannys. I tried to start it and it did not start. I put a new distibutor on it ($175). I put a diagnostic computer on it. New wires. I can not figure it out. I am getting spark to the distibutor but I get no spark to the wires doing to the spark plugs. Can some one help me with this?

    After having an aftermarket stereo installed recently (which may or may not be part of the problem) my battery began to drain while the ignition was switched off. I took it to a dealership, who informed me that it was due to improper charging (the alternator is new), and charged me to clean the alternator grounds, which did not solve the problem. I used a multimeter to test the power draw for each fuse, and found that the draw is coming from the convenience system fuse, so I returned it to a different garage, who couldn't isolate the problem, only that the system draws excessive power for about 5 minutes after the ignition is switched off, and then the power draw reduces. At this point I am disconnecting my negative cable every time I park. Please help!
  • I have a 1999 vw Jetta (new body style) and I have what I think are electrical problems. I will be driving and all of a sudden, my radio starts going in and out and my abs light flashes on and off then if i come to a stop like a red light, then my car will shut off. I must throw it in park and its starts right back up. I've also noticed that sometimes when I put my window down, my daytime running lights will flash as im putting my window up and down. My car is crazy,(since these things dont happen on a regular basis) when i go to a shop, it doesnt do any of things im describing so therefore they cannot diagnose the problem. I just got a rejection sticker for my emmissions the code that read out says it has something to do with my fuel. I am at my wits end, I cannot afford a new car right now and I dont no if my car is safe. PLZ HELP!
  • try (maff sensor )they always go bad on these cars ...
  • that is the Mass Air Flow Sensor correct?
  • I recently purchased a 97 Jetta, today I was cleaning the battery cables and when I re hooked them to the battery the security alarm went off and the trunk key entry won't work. I turned the alarm off by placing the key in the door and turning until it turned off. However the sound system went to safe mode and the key entry to the trunk won't work. I had not seen thid before, so I researched the service receipts from the previous owner, she had numerous issues with the security alarm going off by itself. She took it to the VW dealer on 3 occasions, they finally told her the trunk key entry was bad and was somehow interlinked with the security alarm. They charged her $150 and replaced the key entry. This was in May of 09, now the trunk key does not work and somehow the alarm triggered the event. Does anyone have a solution to the elusive alarm, safe sound system release and the trunk key entry?
  • Thanx so much I appreciate the feedback.
  • My son drives an 09 Jetta and today it would not start. Lights and everything is dead. He thought maybe a battery problem but he could not even get the car to turn over by jump start. Lights do not even come on when the car is hooked to another battery. Any thoughts. Dealer is closed on Saturday.
  • did you ever get your jetta running I have the same problem on 2002 wondering if its the same issue. cranks fine no codes have fuel spark checked other key I'm lost
  • when using my key to unlock the door the alarm stays armed but the door unlocks,when I use the remote everything works,anyone have this problem?
  • I have a 2006 VW Jetta,
    I pass charge from other battery to mine because it was dead, at the moment when I turn on the car all the indicators in the dashboard turn on, at the time when I drove this indicators turn off but the brake and the ABS indicators still flashing and noising on an intermittent way. I sent my car to a VW service, the car was tested with the scanner and no problem code appears on the test result, the people in the agency told me that the computer are ok but they can´t give me a an answer to fix the issue.
    Somebody can help me to have a guide to fix this issue?
    Thanks in advance
  • I have a 97 jetta with a think to be an electrical problem, here's the deal: My car is not garage kept, i live in the north and it snows. There was a pretty bad snow storm and my car was covered in about 3-4inches of snow.*Will get to this later.

    A couple of weeks ago, maybe a month, my cars alarm system and automatic locks from certain key positions stopped working and my red indicator light does not show anything (normally it would blink red when activated), so i have been locking all my doors manually inside when out. Two nights ago i was going out to families and my passenger side door would not open so they climbed over from the drivers side. We just figured it was the cold and the lock was frozen when i hadn't been locking it at all and the door was not locked.

    Last night was when my car was covered from the above story, when we went to get into my car i opened my drivers side door (which hadn't been locked) and the car alarm which hasn't been activated from about a month started going off when ever we opened my door or the hood and the luggage compartment would not open at all. We popped the hood which also activates the alarm. My alarm apparently voids my ignition so just to get my car started i needed to hot wire my car by bypassing the ignition system.

    Now today, i went to try and fix the problem, and first thing was that i checked was if my drivers side door would open, it did, then i opened my door to pop the hood which should have set it off (the alarm shuts off after 4mins.) it didn't, so under the hood i taped up what i striped to hot wire it, then i opened my door a couple of times while slamming it and then it finally set off the alarm, since my side hadn't been working to lock the doors i went to the passengers side door to unlock all and it had shut the alarm off.

    My question is first: Has anyone had a problem remotely close to this? Second: And if so, what did you do to fix it. And third: Was this possibly just a short out of my alarm system getting wet?

  • I have a new battery, had the alternator checked and a new ground wire. When driving with the lights on and sitting at a red light with the turn signal on., the dashboard lights flashed on and then off again several times. I could hear a clicking noise as this was happening. Later, while driving, a red light appeared for just a moment in the speedometer and I heard 3 loud beeps.
  • UGH! I have an 03 VW Jetta & had my car diagnosed about 8 months ago, (with a very reputable foreign car shop) because the CEL light was on. They said the problem was the thermostat. I just had the thermostat changed with another foreign car shop & the CEL light turned back on, just a few days after the thermostat was replaced. So now what do I do??!! What could be the problem? I also have another problem; ever since ive had this vehicle, when I take off from a stopped position, there's quite a delay & when I step on the gas to try to pick up speed, the car leaps forward. Any idea's? :sick:
  • It sure seems to me that there are a lot of electrical issues on these Jettas. I had heard from a friend in the business to stay away from these models of certain years but have never owned one myself. Well, my brother recently bought a '97 Jetta from an older woman and the car has around 90K on it he says. I told him about this site here at Carspace and that he should come in an browse the topics so as to give him a heads-up for things to come. He told me on Christmas day at our mother's home that the car already needed a transmission. He knew this when he bought it, and I'm sure he got the car for a good price. He found someone here locally who specializes in VW's and he's going to have this tranny replaced with a rebuilt one for around 800-900 bucks. He's getting rid of a big Chevy van that he's had for years and gets about 10MPG's on a good day. He's a privave duty nurse who works long hours and wants to benefit from a car that gets good MPG'S and is fairly reliable. Some of the commentary I've read here suggests that these Jetta's seem to have their fair share of gremlins! If there's anything in particular anyone can tell me to watch for with these cars I'd appreciate it and I'll pass this on to my brother, unless he comes in on his own soon. He's not fond of computers, but he does have one!! Thank you!
  • so i got in my 05 GLI this morning and my headlights, turn signals, heater/ac, high beams, rear defrost, and windshield wipers wont work. the hazard flashers work and the high beams will work with the temporary function. I checked all the fuses and didnt see any problems there. has anyone had this problem or have any ideas? id greatly appreciate it.
  • Well, I have a 06 VW Jetta TDI. Over the summer the entire climate control system just stopped working. I have the a dual zone system and everything lights up like it is working but no air blows from the vents. I've taken it in for repair 3x with no luck. Each time the #4 5 amp fuse was replaced which would later blow in a matter of days. The last time I took it in the AC pressure control switch was replaced and the fuse blew before I got out the parking lot. The owner of the shop basically told me he did not know what the solution was to the problem. So I am left with a care that does have have any heat or air unless I change the fuse just about everyday once the blows.

    Does anyone have any ideas about what the real problem is. It has to be electrical?? It was suggested during the last repair that the climate control module may have to be replaced.....
