What will this AC repair set me back?

finaltable · 06-05-2007, 02:21 PM

I assume someone here has had this same problem at some point.

My AC blows cold but the fan doesn't always blow. The air coming out is always cold but it doesn't blow hard very often, even if I put it manually on High. I can hear the fan turning slowly in the dash. Any thoughts on what the problem is?

You have yet to delete it and save yourself the headaches, that's the problem.

It's one of the best mods you can do. IMO.

AC delete doesn't much at all for power increase. Unless you want to be a sweaty mess and make your car the car that nobody wants to ride in, or your low on cash, i would get it fixed

Its hard to diagnose a problem like this over the internet. but i would check fan connections and check connections in the control head.

I bought this car to be a cruiser, not a race car. It has to get me around the Southeast and get me there presentable to meet with clients. Summer + South Georgia - AC would not win me any points with management or wife.

Every time I get an estimate for any AC job it allways seems to be around 500 dollars and comes in a little higher when the job is done. Thats in the USA
and usually getting a new compressor and gas etc. In your case the Matrix will probably need to be taken apart cleaned and the motor checked. These cars have almost 20 years of dust buildup in there so it could be just really dirty and its gumming up the works. After mine was cleaned up it had more flow and didn't have that dusty smell when initially started.
I live in Kuwait and it cost me about 120 dollars to have my system cleaned re-gassed and put back together. Freon is cheap over here not like the USA. In the USA get freeze 12 and you can charge it up yourself cause its CFC free and you can buy it from most auto parts stores YeeHaa! Mechanics though I beleive aren't allowed to charge a car with it but I asked a mechanic in Phoenix when my 72 K/5 Blazer was getting a new compressor what that case of freeze 12 was hiding in the waiting area by the soda machines and he told me it was a replacement for freon 12, cfc free. I asked him if he could charge my blazer with it and save about 200 dollars and he said they can't. I asked if other shops are using it and charging for freon 12 and he said "Absolutely". hmmm.

Thanks. When it blows the air coming out is cold; in fact, this morning it was so cold that I was getting chills because I was afraid that if I turned it down to medium fan speed it would stop altogether and cold was preferable to hot. Turns out it didn't matter because the fan stopped a few minutes later anyway but the air was definitely quite cold coming out of the vents. I am hoping it is just the blower motor and not the ac unit itself. Knowing Murphy, the part in question will be the most expensive whichever it happens to be.

Sounds like your fan motor brushes are worn out. Works some, sometimes.

You can get an aftermarket blower motor,
CARQUEST/FOUR SEASONS Part #208949 New Blower Motor Without Wheel 86-92 List $63.12 Net $37.88

(you'll pay between net & list)

or pay more from Toyota.

Also check this info out, as it may also be part of the problem.

Thanks for the link. I just dropped it off at my mechanic tonight. He's going to go over the entire car tomorrow to tell me the current state of everything I need to care about. (He's doing this for free because I bring all my cars to him.) I'll tell him about the things I read in this and the other thread. In the past, he has tried very hard to avoid having me spend money unless I have to because he knows he's going to get my business either way so if I tell him about these he'll check them out first.
