I was just driving home from work with the AC on and lite smoke came out of the driver side vent over the radio it quit after a 10 seconds and then happen 15 minutes later for another 10 seconds. Has anyone ever have this happen or know what it is?

 

Was there an odor?
If no odor could it have been humidity? Maybe your ac needs a recharge ?
Bad guesses

 

My guess was humidity i live in pa and its been really humid plus a lo of rain but wasn't sure. It didn't smell weird and the ac is good with the fan speed on 1 it freezes me out

 

Take a look at the connector behind the glove box. The resistor for the fan motor is known to get hot and melt (low speeds make more heat). Mine smoked and then quit the next day.

 

Yes, from almost 8 years ago.... https://www.hummerforums.com/forum/h...oggy-cab-7155/

 

LOL, I read his post all out of context. Makes it mean something else altogether after reading your old post Doc, I thought he meant the fan was going out on him, lol.

 

Yep

 

Crazy
