There is a sensor in the back(upper left side of the engine) , close where you do your freon refill. Here's a picture link ( its the black thing i circled ) http://img74.imageshack.us/img74/378...960fulleo3.jpg

 

Thanks! We'll start with the above suggestions. I'll get back to you if I need more help.

Ok, we just checked the A/C. Pressure was at 40. My husband lowered it to 23. The compressor attempts to turn. It turned a couple of times then stopped, another time, it barely moved at all.

Somebody mentioned a sensor. How easy is that to replace? If we need to replace the compressor, can that be done ourselves? How complicated is it?

I hate it when cars become money pits!!!!!!!!!!

 

Sensors are fairly easy to replace but when it comes to compressors (yeah they're easy to take off but u have to let all the freon out and if u dont do it carefully its a disaster) . I'd say u take it to shop and let them check the A/C sensor first.

 

That sensor is called the low pressure sensor. It senses the suction pressure to the compressor, and is what trips it off or allows it to cycle on. Does the A/C clutch stay engaged for awhile or just kick on and off?

 

The clutch barely moved or not at all. Does a shop have to check the sensor or can we take it to Advance Auto and have them check it.

I can see it already that it has to go into the shop just to get the refrigerant removed. $$ [:'(]

hehe. I am trying so hard not to take it in to an auto shop. $$$ saved will go to my next Hot Rod tour in 07.

 

Rather than waste all of your time/money troubleshooting this..take it to a shop that credits the diagnostic fee towards repairs.
An A/C diagnostic will run between $40-60.

Guages for testing the pressure yourself will run $20-45 and that doesn't mean you'll figure out the problem either.

There are some automotive systems I don't work on myself because of what's involved. Once you break open your A/C system you MUST replace the Accumilator/Drier and have your system evacuated to remove all moisture. Moisture = corrosion.

Take it to a shop, have them do a diagnostic and if it's repairable by you, then do it. But if they have to open the system. Weigh the cost of doing it yourself vs. the shop.

 

I guess I was in denial. It has to go in. Thanks Derf for putting into perspective for me.

 

A/C inspections usually un from 20 to 25 bucks

 

She's going to try a few things at home first. A friend of mine who is a mechanic gave me some tips and we'll give those a shot.
