Abs/tcs lights on and turn signals light up

[amanda29]

Hi....

I am having a problem with with my abs and tcs lights. They are coming on and staying on. when I push on the breaks both turn signals light up. when I push on the gas they go off. I am not hearing any noises or anything and it is driving fine. I have noticed that the inside dome lights will flicker sometimes and the break and head lights seem a little dim. The left trun signal works fine and the right one goes fast but will go back to normal after a few seconds. Can anyone please help.

Thanks

I feel your pain... but unfortunetly I don't have any advice for you. The fast blinking signal light usually means you have a blown bulb but in your case it's sporatic... loose bulb?

From what a hear about these vans they can be an electrical nightmare... which I'm not looking forward to!

I called a few places today and they want 75.00 to 80.00 to just run a scan on it. I am so not looking forward to having it fixed sounds costly and to not mention that we have not even had the thing for a year. If anyone else can help please do!!! Thanks

i'm having the same problem as you actually, only mine is alot worse, my turn signals are lit up and the ABS light is sparactic, however i have zero tail lights except for the 3rd brake light which is constantly bright, when i use my left or right signal it flashes, and the only way the tails themselves work is with 4-way flashers and even at that they are few dull

HAve you checked the fuses? I was going to have my husband try them and see if anything is out and try and replace the tulbs. I don't really have the money to have the scan done on it and get it fixed, the holidays are such a bad tiem to have things happen to cars. I have heard alot about a back harness to rear taillight, that it maybe out or have a short so that might be something to have looked at. This may help someone.

Probably a short or ground issue on one or both rear circuit bds. (tailight assemblies). Make sure that your plug in harness connector hasn't shorted as well, as my 97's did. Both rear brake lights out, only third brake light on, as well as ABS and TCS idiot lights on. Cruise control not working either. You may have some or all of these symptoms, but it is probably the start of them. Pull the wire harness end off the plug to see if the middle contact (black wire of the harness) looks defective in anyway. If it looks a little burnt or its mating plug does, you have the famous short. If you buy new circuit bds (taillight assembly) only to solve your problem, goop weatherproof silicone caulk over the connection on both sides once you prove it works to prevent this shorting out from happening again. Design flaw by GM. Who would ever place any connection in the direct drain path of the rear hatch. The other option you have which costs about $5 is to label the harness wires that plug into the circuit board as to their location on the mating plug, cut the plug off the harness, attach connectors to each wire, cut down all 4 sides of the circuit bd plug about 3/8th to 1/2 in exposing the 5 pins. Be sure to clean off the shorted middle, thin prong/pin carefully. Attach the mating connector from the location markings you did earlier. Test the brakes, notice that your ABS/TCS dash lights are now out, and apply weatherproof silicone to the connections so that water, etc cannot collect at the harness or connections. The McGyver way, but my circuit has worked for over a year incident-free. email me separately at [email protected] to discuss more. Thought my ABS or Traction Control was on the fritz, but low and behold, only after looking this up on AF did I discover the problem and fix. If you go the new circuit bd route, the circuit cards I saw on Ebay recently were $27 US each which is a good deal. However, you still need to either replace the wire harness to them or perform the strip and add connector way I describe above. Good luck, Corey
