You are better off replacing the whole compressor. You can purchase a remanufactured compressor for $30 more and it comes with a 1 year warranty. Also replace the dryer/accumulator with this. It only has 4 bolts that hold the compressor on and it's a one for one swap.
First, remove the hoses from the dryer SLOWLY!!! This will allow the system to depressurize. Once the air stops hissing, remove the front and rear connectors from the dryer. Remove the 4 main bolts from the compressor and the one bolt holding the hose connections. Remove the serpentine belt and lift off the compressor.
CAUTION****** Drain the oil from the compressor and fill the new one with the same amount of new GM AC oil. Install the new dryer and the new compressor.
After installation, I suggest taking the vehicle to a service shop and have them vacuum the system and recharge it. You just saved yourself approximately $400 anyway, so having a professional perform these tasks is only a few dollars. This could save your new ac system in the long run.
hi, i need to know how to replace the heater core with a/c on a 1994 gmc jimmy. a diagram would be helpful
How do you replace the heater core on a jimmy?
I need to know how to replace a heater core in a 1992 GMC Jimmy?
It is located at the front of the intake manifold between the A/C compressor and the alternator
If it is 4x4, you have to replace the whole hub
How do you change the abs pump on a 2001 gmc jimmy
the battery is flat
I replaced the water pump on our 98 jimmy last motnth you will need to star with removing the raditor and the fan clutch fan. Once these items are removed you will have a clear picture on the water pump and the bolts that need to be removed.I am not a gear head and this took me two hours from start to finish.
It wont shift because its leaking fluid.
The A/C clutch engages and disengeges when the pressure in the system is too low. The most likely cause is that it needs to be recharged. If you recharge the system, make sure to use R134a and purchase at least a small pressure gauge. You can also purchase a hose that lets you fill the system right from the small cans of refrigerant. All of this can be purchased at your local auto parts store.
need vacuum pump to remove all moisture and contaminants in system
The 1998 GMC Jimmy air-conditioner low pressure for is located on the top of the air conditioner compressor. The low pressure port will be marked as such.

Make sure its the ac compressor making noise. The idler pulley and belt tensioner can make alot of noise, also. If you haven't replaced those, I'd start with that as it's a fairly inexpensive fix. If the noise doesn't go away, no harm done because those components should be changed every so often anyway. (belt tensioners lose spring tension over time). If you're sure it's the ac comp., the compressor bearings are probably going bad and you'll need a new one. I have a '99 Jimmy and the comp. started leaking oil from the front seal a few months ago. Still blows could air, but recently started making noise. I'll be replacing it real soon.
As stated by the band on their official website, they are not sure who is going to replace Jimmy yet. They don't know if they even are (or ever will be) ready to replace him. They have replaced him with two temporary drummers so far, those being Mike Portnoy of Dream Theater and Arin Llejay.
the a/c system has a pressure sensor to it, it's on the accumilator @ the rear of the eng compartment. try using a wire to jump it if the a/c works after that tere is your prob
