If you say clutch comes on, did you try feeling the suction pipes. If its not cold enough, you may have a poor ac compression. If its cold indeed, then the cold air may have been diverted elsewhere and this is caused by faulty hvac door actuators or faulty air mix controller. ?
You might interupt the security system thats on your vehicle. If you make the switch and the security icon pops up on the dash. That vehicle wont start ever again. at least till you fix the security. Is there a little black chip in your key? Thats a dead give away, If there is a chip, you'll have a one in 15 chance that it will work.
According to my parts guide, the fuel pump for your 97 Olds Aurora fits only that and the 97 Buick Riviera's and nothing else. The pump for a 99 Park avenue comes up as a different part number. Hope this helps!
Not sure how different, but on the 2001 4.0 you remove the fuel rails and intake manifold. Starter is under the intake manifold. Not too difficult of a job.
GM Shop manual would be the best.
I did this on my 01 V6, and even on that I had to remove the cross member above the radiator, then remove the radiator fans. The manual said you had to remove the AC compressor, but I was able to do it without removing it.
Several- The system should hold freon for years without leaking. There are pressure switches and they cut off the compressor with an undercharge and an overcharge. You need guages to measure the charge. There are testers the A/C shops have called "sniffers" which can detect a leak. If you have no leak then you need a technician to add or remove freon to get the concentration right. Or you need guages.
GM products have a safety feature which shuts down compressors is they run too low on refrigerant. Honestly surprised you were able to fill the system with refrigerant since the compressor would have shut off. The best way to reset the compressor is to disconnect the negative battery cable for 15 min. After reconnecting, the compressor should function again assuming there's enough R-134A in it. If there's not, turn the AC to MAX and add the refrigerant. At this point, the system should actually **** the can dry. Hope this helps with your AC problem. All the best! Greg
