2001 suburban air condition wiring diagram

My air condition in my suburban intermittently stopped blowing cold air. I checked the refrigerant pressure and it was good. I even added a little R134a to make sure the pressure was at the max. When I disconnect the wire harness from the low pressure switch (in the side of the evaporator) and jumper across it, the A/C works great (of course the compressor runs all the time). Is this a bad pressure switch or could it be something else? Do you have to evac the system to replace the pressure switch?

I would change the pressure switch and it just turns in and out and it won't loose R134a. The one switch should be on the dryer bottle with two wires plug.

By pass both pressure switches one at a time with small wire or a paper clip. If comperssor kicks on replace the swich that you bypassed.
if not it could be the fan clutch ot the compressor. Compressor runs about $400.00

Found the fix on another forum - replace the AC clutch relay in the power distribution box under the hood.

This has worked for at least two people with this exact problem so far.

105 psi? If so that is way to hi...especially for a mid-sized car. You ideally want you pressure to be between 40-50 psi. If you pressure is that hi you might have blown the pressure valve on you compressor, which is not a part that is sold seperately. You should take your car to your local Pep Boys and have them run a A/C diagnostic which runs around $45 to give you an better idea. If you don't know what you're doinf the A/C system is not something you want to play a guessing game with. Especially since it's illegal to work on it without the proper tools and licenses.

Air conditioner blows cool not cold air


- Keep the knob on RECIR and not FRESH.
- Put the air con ON, blower on max speed.
- Open the hood, inspect the inspection window glass located on the liquid line.
- If foam like bubbles are seen, charge the refrigerant gas, till the glass window is seen clear. Never overcharge the system.
- If the problem persists, check the following:
Refrigerant volume
Refrigerant pressure
Heater control base (for Hatchback)
Heater control base (for Sedan)
Air conditioning pressure sensor
Compressor and pulley
Expansion valve -
Air conditioning amplifier
ECM
CAN communication
The following diagram may help you identify the components.

Hi bensarabia,

This condition is usually an indication that the a/c refrigerant level is low. The driver's side will always get heating and cooling first. I would recommend having the refrigerant level checked and also having it leak tested.

sounds like your system is still low on freon. Is your ac line cold that comes out of the compressor? If so what is your high and low side readings? should be looking for aprox 50 low and 200 high side

Imtermittent fault with Ford Focus air conditioning


Sounds like a leak. If you've had to recharge the system every year, you're losing refrigerant. If you've added refrigerant on your own, you may have overcharged the system. The best way to find out is to get a refrigerant pressure gauge and check the pressure. A reading between 30-40 psi is in the normal range. Below 30 will require a recharge, above will require releasing refrigerant.

Would like to recharge my air conditioning on my 2001 nissian maxima that has 117,000 on it blows hot air when air conditioning is turned on.


You will need R134a, and a filler hose. Charge the system on the low pressure side, it should have a blue cap on the charge point.
Your filler hose will only fit the low pressure side, just in case the cap has been removed.
