Chevy Venture Electrical Problems

bishop942bishop942 Member Posts: 4
Does anyone know if and possibly where the fuses for all of the interior lights -courtesy inside rear. There are no lights going on and I can't seem to find any fuse for this problem in the fusebox under the hood. I checked the bulbs and they are good they just don't work. Any help will be greatly appreciated.

    Have you checked that the activation switch has not been accidently turned off?

    Thanks for the reply. Unfortunately the only switch I really know about is the little wheel switch on the left hand side of the steering wheel. (rolling it all the way to the right) if you could tell me about where it (the activation switch) is I could definitely check it. I have googled "Chevy venture activation switch" with no results. Once again thank you for all of your help

    The switch should be located in the overhead switches on the ceiling.

    Yes, the official name of the switch is the "Interior Lamps Override Switch" and is located in the overhead console switchbank. (At least is is on my 2000 Olds Silo.)
    When he was younger, my grandson liked to mess with these switches and sometimes left the interior lights turned off.

    Thanks for the reply. I do see a switch on the overhead console, one with a light with a crossed out circle on it. When the regular headlight are on. The button/swith lights up. also when I rotate the dimmer switch that button also dims. I flip that switch and the lights still don't work. If you have any other suggestions I will greatly appreciate them. Otherwise I'll have to get a test light and start behind that switch.

    Sorry the easy fix was not there. I guess it's the old test light after all. A wiring diagram might help. Not sure where to get one.

    On my 98 venture, the radio control lights go out whenever the headlights comeon. It is kind of annoying because we can't tell what we are listening to from about 5pm til 8 am. :) Has anyone run across this on this van? Is it possibly a short somewhere?

    Thanks,
    John

    When the headlights go on the dash lights (including radio lights) are dimmed. The thinking is that the lights need not be as bright in the dark to see them. The dash lights are also manually adjustable, with a horizontal wheel to the left of the steering wheel (I think).

    Thanks, but I have tried that already. That is what I thought initially but it didn't fix it.

    Any other ideas?

    ronsmith38ronsmith38 Member Posts: 228
    Is it only the radio lights that go out? If so, that is somewhat of a mystery. If the dash lights also go out, then it may be a faulty component in the switching circuit when the head lights are turned on.

    Yeah, it is only the radio components. That is what makes it strange.

    Thanks for the reply. Sorry about the time. I did in fact find a way to reroute. I took that overhead console apart and shorted with a piece of wire. (at the switch) I don't think it works like it originally is supposed to but at least I can get some light. there is a power supply on that switch that actually lights up the actual button. I used that and now the interior lights dim with the dimmer wheel. I keep the wheel rotated as far right as possible (without the click) and just use the overhead switch to turn on the interior lights. You have been great thanks for your help. I hope this kinda helps for anyone else having this problem.

    A while ago the rear vent windows stopped opening. Then the rear wiper and washer stopped. Is there a common wire harness or connector that may have come apart?

    rlp50rlp50 Member Posts: 13
    I guess this is a bit similar to the post by bishop942. The dash lights don't work when the headlights come on. It is intermittent in that it might work one time and not the next. The overhead console switch that powers the interior lights also has a small circle with a line through it on the switch that, unlike bishiop942's problem, does not light up. Probably isn't the dimmer switch as rotating the control dims the lights on the radio and when rotated fully turns on the interior lights. The overhead console switch also seems to work fine as it turns the interior lights on and off. Any ideas?
    Thanks, RP

    I bought a manual and got the wire schematics. Found the wiper fuse was blown and fixed that problem. The rear vents however, still don't operate. Their fuse is good. Schematic shows a black wire from the front switch to the rear motors. Along the way it switches to a brown wire. Anyone know where that junction is? Motors can operate independently so I am still looking at the common line. thanks

    The main and auxiliary fans in my 2001 Chevy Venture have stopped working causing my van to overheat on occasion. Along with the fans not working my compressor also isn't kicking on as they stopped working relatively at the same time I think this points to an electrical problem. I have checked the fuses and they all seem good. Any ideas would be greatly appreciated. Thanks. :cry:

    I have a 2001 Venture Van. When I put my van in reverse the turn signals come on dim and solid. When I turn on a turn signal it clicks fast like a lightbulb needs replacing. When I turn on a turn signal and the brakes together, the reverse lights come on. I have replaced all the bulbs with the correct bulbs and replaced a bad panel in the rear. Still having the problem. I can't signal to turn at a stop light or intersection, just waiting to get a ticket. :cry: :confuse:

    Well, I've got the same problem with a 98 Venture. Fuse for interior lights keeps popping. I'm not sure where to start.

    Ihave been having the same problem, I looked at the connector to the rear light assembly and the wire in the middle of the connector is melting away the plastic I replaced the connectors and it worked for a while ,but now it has melted the new ones and is not working again. If you find the problem please let me know. :confuse:

    I have a 2000 Venture that had the same problem. GM claims it has to do with moisture getting into the contacts causing an increase in resistance thus causing overheating (to the point it sometimes melts the plastic on the bulb). They suggest using Dielectric grease on the contacts which is a good idea. Mine was always dry so not sure about their theory. I finally changed to a Philips bulb as it seems to have a better plastic base for the bulb (same number - 3057) and stands up to the heat better. The base is clear and must be a better grade of plastic than the stock black ones. Anyway, that plus the grease seems to have done the trick for me. I have also heard that if you keep the brakes on for a long time it also causes the bulbs to overheat. However, it has only ever occurred on the driver's side. Bottom line is it's a crappy design and they should go back to the old bulbs with the base contacts. Oh well, progress and technology, what a mix. Hope this helps.
    Cheers,

    It took me a few calls to the junk yards. I found the whole light unit with connectors for 1/2 the price of what a connector costs at a dealer. good luck!

    Have you gotten this problem resolved???

    I have the same problem with my 01 Venture. I have checked the fan motors replaced the relays, checked the temp sensor, still the 1&2 cool fans dont work and the a/c compressor wont come on. If I figure this out I will let you know.

    2001 venture, I love this truck, although it has few minor problrms, like any other vehicule i've ever owned, this is so far my favourite one to drive...I have a flickering light issue, all my lights flicker, all the time, inside and out. fuel guage is acting up, and sometimes some wierd stuff explainably happens.

    Any thoughts?

    I just purchased a 2001 Venture for a very good price.It needed a few repairs I was able to do myself.
    The Airbag warning light remains on after I start it up.
    Also my temp gauge stops working sometimes.
    It will start out working fine and after driving for about 10 miles or so it just goes down to "C" and stays there. I have an after market scan tool so I am able to see the actual temp of the coolant. I drove to work and the gauge stopped working on the way. When I returned home, both fans were running and the scan tool indicated the temp was 167 degrees. I found this strange because I had just driven 70 miles on the freeway.The intake gasket and the thermostat was just replaced the cooling system just flushed (3) times. I Did not use "Dexcool". A very good GM mechanic of mine which I trust with all of my cars (22 years GM Exp. with heavy repair) says that "Dexcool" crystalizes and plugs the cooling system. (You can see for yourself when you remove the cap on the radiator and overflow bottle.)I am wondering if there is something I can check to fix these problems. TIA

    I have a 97 venture with two electrical problems.
    The 1st to appear was the door locks would unlock themselves repeatedly while driving or parked. Checked door locks and BCM (body control module)No luck.

    The 2nd problem started a few weeks later. There is a sensor below the windshield that brightens the radio display in daylight and dims it at night. Now the radio is normal in daylight unlit at night.

    I have heard mention of some troublesome connections/splices in the venture wiring under the carpet. Could this be the problem?

    Just bought a used 2002 Venture. No owner's Manual.

    The interior lights do not come on when the doors open. They work, but only when I manually turn the lights on.

    Is there some switch I need to hit to allow for them to come on automatically?

    Also, the back seat overhead controls for the heat also do not seem to work, even when I put the front switch on "R"...any help greatly appreciated

    Had the same issue with our 2000 Venture - replaced alternator -no more flicker. Get a remanufactured alternator - the GM OEM ones had weak voltage regulators.

    Low voltage in any vehicle can make the electronics do weird things - if the supply voltage isn't right it gets everything "confused"

    Good Luck - these alternators are a royal pain to replace. On the 2000+ years you rotate the engine forward to get to them, I believe before 2000 you get to it from the bottom by loosening or removing a frame part

    Sorry first time I do this. My 2002 chevy venture van is having electrical problems. I did take it to the chevy dealer but will cost me more then $750.00 to find a power wire number 1340 that is not getting power from battery to module. As the repair man stated if its disconnected he will reconnect it, if its frayed he will tape it, if its corroded he will replace it for the unbelievable price of over $750.00 estimated. If anyone out there has any info please write me back. Just in case this is what is happening I have no tail lights, no dash lights, and no auto daytime running lights but i do have manual headlights and tail lights. Thanks to all who help!!!!!

    If you know where this powerwire is , why not take it elsewhere (a place you trust) and get some more prices. Or, you can buy this wire yourself and just pay for the labour at a cheaper place. Just a thought.

    Hello...

    I'll assume you're talking about the front HVAC blower. You may want to check your blower motor resistor - (its located right behind the blower motor in the passenger side wheel well) but typically when they fail you lose 1 or more speeds on your blower.
    But I'm thinking that your fan speed selector switch is shot - sounds like its sending voltage to the resistor even when you put it in the off position. Its a pretty simple circuit so its got to be 1 or the other.

    BTW - blower motor resistor failures are common on Ventures...just not sure its your problem in this case

    Hi All,

    I have a 2001 Chevy Venture that is behaving a little strangely.

    It appears that the brake lights are not working at all. When we depress the brake pedal the intensity of the lights do not increase at all. I also took the lights out of the housing and noticed that the second filament does not light up when the brake is depressed.

    I have replaced the bulbs with brand new ones.

    What could be causing this issue? Is there something wrong in the electrical?

    Thank you for any help ... if there is any information that I could add that would help, please let em know.
