The cause of no heat!!!!!!!!

No heat fopr like two weeks!.. finally found the problem.. before i went and ripping the bottom of my heater core cover off i tested this little bastard!.. you have to take out your heating/a/c electonic unit out.. paint in the tushie to get too!! got a new for like 75bucks from B&I. Not the cheapest thing but not bad for having heat agian.. you dont relize how much you cherish heat till its gone!

Yikes! That doesn't sound good.

Thats great... but what is this?

If you look real carefully at the top of the page, it says blend door actuator.

My Chebby uses the reliable old school cable. So there.

I just bought one too... looks like autozone ripped me off tho... mine was $135... I just got it in the mail last week and now that it's a balmy 65 I don't think I'm gonna have to worry about it 'til next winter!!

This little, but hard to find (reasonably) piece, can usually be found cheaper at a junkyard. Wagons and sedan got them both, I believe. It does exactly what its name indicates, blend hot and cold air, so you can adjust it to your comfort. Usually bad actuator = cold air.

Yes they are in the sedans. I have passed a few in the yards, maybe I should pull a spare.

I replaced mine on my '95 BRMW a while back. Same symptoms, cold air only. After i put in the new one, I tested it by watching the round hole via an inspection mirror as I cranked the heat all the way up, then down again. The bushing in the hole will turn as it operates.
If you suspect yours is bad, this is a good way to check it. If it does not turn, it is bad (or bad connection).

So I take it this is the same part for 91—96 the heat totally died in my 96 this morning there is a 92 I could get to easy..........lol
