06 colorado turn signals don't work whe the weather is cold. Emergaency flashers do work. When the cab is warmed up the turn signals work. Talked to a chevy dealer, they said they never heard of that before. Anyone have an idea?

new one to me...is it in warranty??

No, it has 83,000 miles on it. Do you know of another website that may be helpful? Wiring diagrams or anything that would give me a place to start looking?

Have the same problem on 05 colorado been to dealer 3 times, last time they called GM factory and they said it needed a new insturment cluster to fix problem. The part has not come in yet so I don't know if that will fix it.
Mine is under warranty thank the good lord.
This is one of many problems I have had ie: Brakes went out almost crashed, brake light switch out 3 times, stereo speaker problems driver side replaced 2 times and out again squeek in rear they can't find or fix, various knobs falling off, heater fan chatters, all this and only 22,000 miles.
MY LAST GM PRODUCT.

Thanks for the input. Please keep me up to date if the instrument cluster thing works. Did the dealer try to change the turn signal switch? What did they try?

Have you check youre relay's?

No, I haven't. Didn't know there was relay. Where would it be located?

The insturment cluster fixed mine. It was -1 this morning and they worked fine.
GOOD LUCK!!!!!

If under warranty, get it done from the dealer. m sure it'll help
