My A/C stopped blowing cold air, so I went to get it recharged. Turns out there was plenty of refrigerant.

The shop said there is a problem with the low side pressure (it is equal to the high side pressure, 200psi). They said the problem is either restriction in the orifice tube or a bad compressor. Then they said if there is restriction in the orifice tube, it is because of a faulty compressor. They recommended a replacement of the compressor, which they estimate to cost $1000-1100. :banghead:

That just seems somewhat dramatic and costly. We bought the car about a month or two ago from a private party. It seems way too coincidental for such problems to arise now (considering it is a '97, there was plenty of time for these problems to occur before).

But it is a problem nonetheless, so is a compressor replacement really necessary, expecially at that cost? Or would simply replacing the orifice tube be enough (if restriction is the problem)?

compressor sounds right, cost is a bit high if full, but the filter drier has to be replaced,refrigerant evacuated, a full system check done, orifice tube replaced (safey concern)reman compressor runs around $400 (at advance)so if they are using a new one price isn't that far off, but still a little high (list is $1000 for the compressor)I always like when people lose a/c and think a recharge fixes it though, if it needs a charge it's broken refrigerant is not used up it's a sealed system, and if needs filled it means there is a problem.It going out now is probably just a coincedenc

arch your right i just had ac class its a sealed system and if the compressors gonna be replaced the condensor has to or it will void all warrentys... it could be a cloged orfice tube..alot of what u pay for is the evacuation, recharge b/c them machines are expensive. they'll also perform a stop leak test b/c if thats in the system the whole thing has to be replaced...

I have seen new compressors on e-bay for 250 dollars, and rebuilds as low as 150 bucks. I'd get it there, and take it to the mechanic.

I wouldn't buy one off ebay for that much considering there will be no warranty, and who know what you get, also does it come with a clutch (the advance one does, most don't and that has to be repalced)some shops won't install someone elses parts either (especially electrical)

jessica2112

Some do have warranties, just depends what you look at.

I got screwed buying a starter on ebay... Tho I made out like a bandit on an alternator. So it could go either way.

BubbaV6

That'd work, but its about 100 degrees outside, so it doesn't help much at all.

I'll look into getting a refurbished one and getting another mechanic to do the work. I'd rather have no A/C than pay $1000 (or more).

97z2801ss

yea A/C systems are expensive...

archemedes

they say they do, but most companies void warranties on compressors if not installed by a certified tech, and they want a service order showing the exact unit you bought

97z2801ss

also they void the warrenty cuz u have to replace the condensor or evap aswell

Why does the condenser need to be replaced? As far as I know only the evaporator and orifice tube have to be replaced when a compressor is changed.

archemedes

gets full of garbage when the compressor pukes, it can technically be cleaned with forced air, but you have to be careful not to add moisture
