Smile Rear AC relay?

Hi folks,

After poking around for a bit, I was unable to find what I was looking for, so starting a new thread.

My Rear AC works for low and medium, but not high. Front AC works for Low, Medium, and (now) High - since I replaced the relay (see http://67-72chevytrucks.com/vboard/s...64&postcount=3 ). Folks on the forum helped me find it behind the glove box.

Anyone know if perhaps the rear AC also has a relay, possibly hidden somewhere equally fun?

Thanks,
-Greg/IrieReggaeMan

Re: Rear AC relay?

not many folks with rear air-conditioners, I'm guessing? I'm on my second rear-AC switch with the same behavior, so looking for other reasons why HIGH doesn't work.

Thanks!

I have a rear AC setup out in the barn I can look at but it is raining cats & dogs right now so it won't happen until it lets up some....

Re: Rear AC relay?

-
There is both a relay and a resistor (on the same order as the heater resistor) on the inside of the rear housing. I'm betting one of those is the culprit. I would visibly check the resistor first to see if any of the coils are broken or touching each other......
