Title: A/C Question
Post by: RunninWild on February 29, 2012, 04:10:00 PM
I've been DD'ing my bird for the past few days, and it may be a while before I drive anything else. So my question is concerning the air conditioning. It doesn't blow out hard at all, but it cold (new compressor/accumulator within past two years). I believe the blower motor is good, as when I change speeds, the system responds by blowing slightly harder and making more noise. I also got under the passenger side of the dash and fiddled with the controls and it looked like the blower would respond. I'm assuming something is clogged (possibly cabin fiter...?) But would like some guidance as to where to start. I don't have the repair manual with me, otherwise I wouldn't be asking.


Any advice would be appreciated. Btw, this is an '88 3.8 car.

I had a bloody mess of a mouse nest in my tbird heater blower motor housing. They love to nest there for some reason.

I guess that's something I'll have to check. Still haven't gotten around to doing this yet (studying & work). Plus it's been pretty nice here the past few days...


If anybody has any additional advice, please share.

Yep, they'll pack the blower cage-wheel between all the fins with insulation from all over the car.  Fan will spin but won't grab any air. PITFA.  They nest there because they come in the HVAC intake at the cowl and once they get to the blower the next thing in line is the A/C coil in the heater box so they usually don't go any further.  3 bolts and that blower housing drops out from under the dash so you can clean it. Take the glove box out so you can reach in through there.

I'll do that. Btw, do these cars have cabin filters? I figured if it did, considering mine has 260K, that's probably clogged as well. Just not sure where it's located, assuming it exists.

Nope, that's a pretty new feature, reminded to us by every little quick auto maintenance guide. But these just take it right from inside the void underneath the plastic snap-in fine grates above the firewall. One time I found a pine needle in the passenger footwell of my crown vic, and no one had ridden in the car for months, and the windows were never opened. There was another one hanging in the recirculating "Max A/C" inlet grate right in front of the fan :hick:

Maybe the pine made it smell good? :)

Same here. One of the first things I did when I bought the car was pull out the blower motor and clean a whole ton of insulation and rat  from it. There was even some near the heater core. I have no idea where they managed to get all that insulation from...
