93 taurus, 3.0 engine automatic trans... R-12 air cond. unit... this morning the a/c was putting out real cold for the 20 minute of city driving.... came back home after one hour at doctors office. and it seemed not as cold.... noticed that when driving it seemed to be getting hotter(the engine is not running hot, just the a/c unit air..)...... i would have to stop at a few red lights about 6 of them and noticed that when sitting there the air seemed to be getting colder. when driving off it seemed to warm up(thought it might be vacuum as there is greater vacuum when at idle???, well when almost all the way home it was like no a/c in the car at all... went inside and had lunch... went back out to car a started it up and it was not putting out anything but hot air... the compressor was not working..... went back in to get the shop manual and started car up and its ice cold, compressor working, pressures correct...... i checked the diverter door for a loose or missing hose, but there is none and it seems that the compressor might not have been working on the ride home which would rule out the vacuum.. any suggestions??????????
I had that same problem with my '94 Taurus. I didn't bother getting the A/C fixed. I just waited a few months before I was able to trade it in for a brand new Taurus.
well i know the feeling, i did the same thing with a 83 mustang, nursed it for 6 months until i could retire and be in the chips to buy a new car.. thats the 93 taurus now.... well it was new, but like anything it get old.. i can get parts for it, but not for me.... thanks.
Do you have a Haynes manual? If not I suggest you purchase one for $10 and look over the A/C troubleshooting section. I had nearly the same issues as yours and Haynes led me to the problem, and the steps in remove the parts to fix it all myself! In my situation it was my clutch going bad, doesn't sound like yours though, sounds maybe like a controls issue if you're lucky. Have you tried adding more refrigerant? I believe this can happen if you're running low. If you're not, you'll know and your system won't suck any outta the can. Good luck,
