yes you have to have freon and oil in the compressor for it to work.

have battery fully charged and load tested.
if good put voltmeter on alternator make sure it has a minimum of 12.35 volt if lower your alt is bad

Sometimes the starter sylinoid goes out. If its a clicking noise its the battery. If nothing try the starter. Sometimes you can tap the starter with a hammer and its good if that is not it test the starter. Start here before you go to anything else. Its the starter most likely.

Thank you for inquirering about my module location issue. I ended up calling a GM mechanic friend of mine and he helped me out. Thanks again and I will probably use your site again in the furture. Don

yes you can get a puller at any local parts store or harbor freight to pull it off

have the wire replaced by a certified mechanic with oem replacement parts

Crank shaft position sensor

I had a 90 Cutlass Supreme that did that too. I just got into the dash and forced the arm on the main gate open.

There is a fusible link for the blower motor. Check that. Don't know where it is. Look up the wiring diagram at autozone.com. Also check the fuse in the fuse box. Could just be that.

Code 22 refers to retarded advance camshaft Position Bank 2. the eaasiest way is to get a known good ECM and replace in place of the old one. if it runs good. replace it.

The heater core is located on the passenger side of the vehicle. If this has been bypass the core is surely leaking. The heater core pipes should be visible from un der the hood, passenger side of vehicle towards the firewall. keep me posted, and keep an eye on that heater core, there is reason for the prior owner not to have heat.

Your transmission is about to give on you, Go to your nearest shop and get it looked at!!!

It is a mute point because you can't do this yourself. Your system has air in it plus moisture. All that need sucking out with a refrigerant gas recovery machine to create a very strong vacuum, then the system is checked for leaks. Only then is the refrigerant gas installed by weight. Freon is the brand name for a gas that is no longer used. There is a sticker in the engine bay that tells you the weight of gas and the amount of oil. This explains, take it to a shop that does AC. https://www.fixya.com/cars/r29878326-recharging_vehicle_air_conditioner ..

The blower resistor may be going bad and need replacing. Does it do it only on one or any fan speed? I'm not sure where that particular part is located for it has been number of years I have looked at vehicles older than 18 yrs. but I hope this steers you in the right direction.

I think you could use this manual method instead.. My nephew used it to repair my car and it's totally perfectly fine now. Here's the website he bought it from. www.reliable-store.com

GM doesn't believe in making things easy. No access panel

How do you know it's surging? In any case, about the only thing that can cause this is a faulty regulator in the alternator, or a poor wiring connection (e.g. battery cable or at alternator).

Have you checked the vacuum line with a gauge? If so, how many pascal units does the vacuum line read? Vacuum gauges are around $5. Furthermore, I believe the design is sealed vacuum only system. The solenoid could be bad, but to my knowledge it is not an electrical component. A split in one of the vacuum lines could be cause of your problem. You would have to trace the all the vacuum lines back to the source to find the problem. You would need that gauge to detect a leak in the system. Could also replace all the vacuum lines on principle since the vehicle is going on two decades.

Sorry Doris. It is the transmission is gone.

On most cars in this era, the pump itself can be adjusted by loosening the mounting points at the front and rear of pump.
