Default Air conditioning not working SL1

I fired up the A/C today only to find she was blowing hot air. The A/C light comes on when I press the button, but I don't feel or hear the A/C engage. The recirc button light comes on and the vents close so I know that the button panel is working.

Any tips on what could be preventing the A/C from kicking on? Fuse?

Do yourself a favor and try some light reading before reaching for the recharge cans; http://www.saturnfans.com/forums/showthread.php?t=80107. You may not want to know that the refrigerant leaked out and tripped the low pressure switch that saves your compressor from damage (by turning it off) if it were allowed to continue to run without gas. The oil needs the refrigerant to circulate in order to find its way back to the compressor for lubrication. Either spend the time to find the leak, then decide if you want to handle the repairs or bring the car to a pro that can do the work.

Hey, listen to fdryer, he knows what he's talking about. As he mentioned, find the "probable" leak and to save yourself some money, try to fix it yourself but if I were you, after fixing the leak, I'd take it to a professional place to have the system evacuated and filled. Also, it depends on how long the system has been empty of refrigerant, but you may want to install a new drier before having it refilled. They can be bought for around $30+ or so from http://acpartshouse.com/listitems.aspx?page=3&&

Good luck,
Jerry

Gentlemen,

Thanks for your replies. This sounds a little outside my bounds. Oil changes and air filters are one thing, a/c is a different class of issue. Too many funky tools and chemicals to mess with.

Maybe I'll just roll with the windows down for a while.

Maybe I'll take it to the shop.

I guess this would be a good use of my economic stimulus check.

I just replaced my drier, expansion valve and o-rings. I got a pretty good deal here: https://www.ackits.com/pc/37-13528/S...+-+Accumulator

PS: A/C is not for the squimish, the hardest part is having the right tools and know how.

Dave,
I thought the same way you do about air conditioning-----and knew nothing. But getting help on this board, especially from fdryer, I continued to look into it and replaced my own drier for about $30 and took it to a pro to have it evacuated and refilled and I'm good to go. There are some things you can do on your own and some you can't. If you want to spend the time to look into it, you'd be surprised how much you can accomplish. Good luck,
Jerry

The weather has been relatively cool here so I haven't been pressed to get the A/C fixed.

I'm still looking for a way to find out if my A/C problem is electrical or with the compressor/system. Any tips on how to determine if the relays and controls are working OK before I tackle the HUGE job of finding leaks, etc?

Thanks

Wow! That's a great set of videos. A true public service.

I'm off to RadioShack to get a multimeter. Wish me luck!

I had a problem with the fuse one time on my 97 SL1 where the a/c wire had wound up on the compressor pulley and it wore off the rubber coating and shorted out the fuse, so check your fuse on the right side of the console and they may be one under the hood, I cant remember for sure before you go to checking for leaks, because the fuse can also cause your compressor not to kick on but if it's not the fuse you might wanna do like fdryer said and check for leaks. I bought some r134a uv dye for $10 and a uv light from autozone for $28 for my cavalier the other day and found out it was the compressor...But maybe it will just be a fuse for you...
