I started the car yesterday and the radio was turning on and off (by it self) and the electric windows would not work.The mirrors still work and all guages work. It sounds like a relay is turning off and on,any one seen this before.Thanks for any help.

    Please can someone help. Ive just found that my right side turn signal lights are permanently ON. If i use the right turn signal i get the clicking sound but at twice the normal speed. The only fuse I have found that turns them off is fuse 59 (instrument panel fuse box). Im no electrician so any help would be greatly appreciated.

    I don't know if you have over 36,000 miles but if I were you I would just take it in. Probably have a short in the electrical line to the tail light assembly. You could check to make sure it's not pinched or bent. If it was a fuse it would not work at all. Good luck.

    Hey guys, found a list of Ford TSB's and detailed instructions on how to fix them. This is very useful, gives you the power to somewhat diagnose a problem you may or might have with your Mustang be able to go to the dealer knowing more information then they do at times. Just be slick on how you go about letting them know the problem. Dealers seems to hate you diagnosing your car yourself.

    These are not specific to the Mustang. For a list specific to the Mustang, as well as the model year, check out Edmunds' list.

    Sounds like a bulb on the right side is burned out.
  • I have had my 06 V6 for 3 months now and use it as a daily driver. It has very mysterious problems that come and go all I think are related to one or more electrical problems. They are so intermittent that the dealer can never duplicate them and has yet to solve them. Some of the things it does:

    The stereo (shaker 500) suddenly becomes sluggish (it takes 30+ seconds to change volume am/fm or turn off. If turned off while in this state it will not come back on. Let it set for a few hours and all is fine.

    Occasionally, after driving the car will not start while hot.

    Occasionally, while driving the transmission makes poor shift decisions and either doesn't downshift when accelerating (even at WOT) or just downshifts to remind me it is there while in cruise on a flat surface.

    Occasionally, after driving a short distance and coming to a stop when starting to accelerate the car stumbles (hard almost stalling) then after a few seconds, takes off.

    These are the frustrating problems not including the list of things that the dealer can fix:

    Left speaker has a harmonic vibration.
    Right door rattles.
    Weather-strip doesn't seal against the convertible top.
    Convertible top has a listing that causes a rattle at highway speeds(front listing).
    CD Player skips unless the disc is new and 100% dust free.

    If the radio continues to do this have them swap it out. The Shaker has had many complaints.

    Your stumbling has been noticed by others. There is a tsb for the fuel system. It also could be due to the drive by wire throttle.
    There are many sites that list the tsb's. do a search.

    I havent had any transmission issues. But many mod their mustang to override the computer to get rid of throttle lag, shift points, etc.
  • Many of the same issues in the past two days. 2006, V6, 10,000 Miles- today- the Electric Throttle light came on as the car basically did not drive any longer on my way home from work. stalled out along the way, started back up and made it home while sputtering. Parked, and then restarted the car and nothing !!!! Al is fine for the moment. Already received my car back two days ago after several seperate issues and it not shutting itself off after a LOW idle. Very wierd and definately trying my patience. :mad: :confuse:
  • Ford knows about this and hopes you wont sue them..... take my advice... call an attorney now and ford will offer you money to settle or you can wait for years and make their asses take their crap back and refund you all your money.
  • :mad: I took it in yet a third time to the dealership due to the car stalling (While driving) 4 sperate times within one day. After it being :sick: for TWO days at the dealership and me in a rental car (also after a HUGE argument)They told me they replaced the Mass Air Flow Sensor. after the replacement- they road tested the care for 34 miles and with no avail, could not get it to duplicate anything. Well, So far, so good on the stalling, etc... I guess we'll see. I personally don't have a great feeling about the car being :) , but only time will tell i suppose. I'll keep you updated. My next move is definately - :lemon: .

    "They told me they replaced the Mass Air Flow Sensor. after the replacement- they road tested the care for 34 miles and with no avail, could not get it to duplicate anything. Well, So far, so good on the stalling, etc..."

    My current car (not a Mustang) exhibited the exact SAME symptoms shortly after initial purchase (nearly stalling out when trying to accelerate; essentially just falling on it's face when I gave it gas and then suddenly going). Dealer's thought it was bad gas/wrong gas yada yada yada.

    Finally they replaced the O2 sensor (essentially the same as your Mass Air Flow Sensor). The car IMMEDIATELY ran much much better and hasn't done the stalling thing again. And it's been 5-years and over a 100k miles since that O2 sensor was replaced.

    Try to have a little faith.
  • Well, AWESOME - I can say that the car does drive like it never drove before. No grabbing, stalling, dying, etc.... Hopefully I got lucky. Thanks
  • For the record, a mass airflow sensor and an O2 sensor (oxygen sensor) are not the same thing. The MAS measures the volume of air going into the engine through the air filter, throttle body, intake manifold, etc. The O2 sensor measures the content of unburned fuel in the engine's exhaust.

    A car with bad MAS typically runs really badly. I personally have never seen bad O2 sensors make a car run badly. (A bad O2 sensor will light the "check enging" light and can cause other problems like high emissions and cataltic converter damage, but the computers in the newer cars seem to keep the engine running smoothly via an "open loop" mode.)
  • Thank you for that. It sucks when you have these problems arise and as we are not all mechanics, it's tuff to trust anyone when they tell you numerous things in regards to what's wrong with the vehicle. I believe this MAS was the issue since day one because it seems to be a completely different animal now. Drives like a :) car now. All of the numerous issues are showing themselves. What a Relief.
  • Got my 05 yellow mustang on 10/26/2004. GT Premium package. V8 auto. Had to. My 1999 got crushed by a tree. In 11/04 had major transmission fluid leak, 325 miles. Had to have cooler line repaired.
    In Aug of 05, with 5700 miles, brakes squealing. All 4 brake calipers had corrosion on them.
    Feb of 06, 9062 miles. Several problems. Car is getting worse. Transmission slips when starting from a complete stop. Dealer couldn't find anything wrong. Replaced a few parts. Interior trunk lock and linkage had to be replaced. Right front dashboard rattled and was very noisy. Dealer re adjusted dash. Rattle came back. The tires began to loose 5 to 10 lbs of air per week. Dealer said the inside of rims were oxidized and they cleaned them. That didn't last long.
    April of 06, 10,315 miles. Had to have car put on flat bed and towed into dealer. Electrical system went haywire. Couldn't start car but all lights on dash were blinking.
    Had to have new battery??? Also had same issues as in Feb of 06. All tires loosing air, rattle in dash getting worse, transmission still lurching from a stop. Dealer said all was fixed when i picked up car. Yeah right!!!
    August of 06, 12,413 miles. Same issues as before, trans slipping, tires loosing air, rattle in dash constant and the big one, engine grinds when starting. That one they had to replace the timing chain. At this time, dealer assured me that all other problems were fixed 100%.

    As of today, the rattle in the dash is the worse it has ever been. All tires are still loosing air, have to keep a tire gauge with me at all times, and the trans still slips. I call customer service, that was a joke.

    I also have the gas shut off problem which i will address when i take my car in on monday.

    My car is going back to the shop on Monday. Anyone have any problems like this.
  • I also have the same problem with the transmission. I have had it into the shop 3 times and they tell my there isn't anything wrong. But my 05 GT is going back to the shop on monday, again. i will let you know if they find anything, but don't hold your breathe.

    Has anyone had problems with water leaks causing electrical problems?

  • I have a 98' ford mustang automatic.The gauges on my dash are not working. This includes the speedometer, odometer, battery, oil,,etc. When I start the car the only lights that come on are the battery light and the theft light. I had my fuses checked @ pep boys and they checked fine. He tested them with the car on of course. Then I asked a friend of mine who is a mechanic and he said it could be the instrument panel fuse and it needs to be replaced. I lost my owner's manual so I'm not sure exactly what it looks like or where it is located. Can someone give me an idea. Also if it is not a fuse can anyone give me any ideas as to what else the problem could be.

  • Anybody have an idea why the map lights on the rear view mirror (05 convertible) would suddenly stay on? I assume there's a sensor or switch somewhere that signals the map lites that the door are both closed and to turn off in a few seconds' but suddenly they just stay on(key out, pushbuttons checked off). Had to pull the bulbs to keep the battery from running down until I can solve the problem. Help?
