When I test drove my car originally the AC was on "Hi" and it blew cold air like a boss. I fiddled with the controls to check the defrost and it blew hot out the defrost vents but kind of hung there...

I used the fouled up AC for bargaining and drove the car home.

On the way home (About 600 miles.) the heat became too much so I pulled the AC fuse to kill the blower.

Somewhere along the way the engine lost the ability to turn off *sigh*

I put the controls back on "hi" and replaced the fuse and the AC was cold again so I rolled with it.

Anyway, this AM the defrost was back on (I didn't manipulate any controls).

I tried the fuse boogie again and nothing. I also noticed that the #3 fuse is REALLY warm.


Sooo,

#1

I'm pulling the pass. side ducts under the dash to check the "recirc" pod. If it's leaking I'll plug the lines. It must be a pretty good leak to prevent the engine from stopping right? The AC vacuum controls are somehow fouling up the engine shut off.

#2

Look at the ACC amp for any obvious defects.

#3

Lube the blower motor. (Causing the fuse to run hot?) Need brushes as well.

#4

Check the auxilliary pump for function. I'm sure it works because the heat seems fine.

Any other advise?

I'm going in...
