Where is my a.c. compressor replay fuse at for a 2000 montero

It is doubtful the fuse is an issue, check the refrigerant charge in the AC system, if it is low the compressor will not engage. You can jump the low pressure switch to turn on the compressor, that will verify the electrics are all ok. The switch is located in the low pressure AC line from the compressor on the engine, it is the larger of the 2 lines coming from the AC compressor.

Where is the low pressure cycling switch?

Low pressure rarely goes bad, it is always on. It works the opposite of the high pressure switch. When the pressure gets to high on the low side, the switch will cut off the compressor. Low switch is usually by the compressor or mounted in the compressor. What's your A/C not doing.

2001 chevy ventura compessor wont run

1. check your a/c fuse to make sure it is good.
2. locate the a/c low pressure switch (should be on top of
the a/c dryer. disconnect it from the dryer and by-pass the
switch with a jumper wire while the car engine is on. if this
makes the a/c compressor come on then quickly disconnect
the by-pass wire to keep from damaging the a/c compressor
(because you are low on freon and the low-pressure switch
turned your compressor off to keep it from getting damaged).

Where is the low pressure switch on a 2000 mercury sable

If you are talking a/c the low pressure switch stops the compressor from working if the gas pressure is low. This is to stop the compressor from running and either sucking in air or running out of oil which circulates through the system. Replacing the switch which should be at the receiver/dryer (that little round cylinder before the condensor radiator) but I suspect that you have a leaking system that no amount of gas refills will fix until something is done to rectify the leak

Ac does not engage

Most vehicles have a low pressure switch that prevents the compressor from engaging so as to prevent damage to the compressor. You need to place a gauge set onto your AC to read the high and low sides of the system. Probably have lost enough gas(R134) over time to prevent the compressor from engaging. You can jump the pressure switch to check it with a simple jumper wire.

Air conditioner does not cool in 2000 Yukon.How do I check freon level and how to replace freon if need be

Get an r134a refrigerant add kit from Walmart or your local auto parts store.

You can even get a can of Arctic Freeze by Intermatics that has a hose and a gauge on it.

Connect the hose to the low side port. You can find this port on the 'thicker' piping that comes off of the compressor (versus the thinner piping that comes off the compressor which is the high pressure side).

Pressure should read 25 psi to 45 psi on the low pressure side when the compressor is running and the a/c is on.

Pressure should read 75 psi to 100 psi on a hot day when the car is off.

However, you'll want the a/c to be running when you add freon.

Press the button on the can to install more freon, if needed.

Hi IM AL the owner of Big As Auto Repair

The cycling switch is what keeps the system from freezing up and comes in different forms for instance. Some vehicles is located inside the a/c housing close to or pushed inside the evaporator, on other vehicles it's the low pressure switch. NO, you do not have to much Freon because if you did the high side pressure would go well past 350 to 400 psi. I would google how to change the cycling switch on your vehicle and watch the video. Hope this helps and have an awesome day. AL with Big A's Auto Repair.

Compressor doesn't get power , the compressor works, there is some type of switch that tells it to engage but the switch isn't telling it to come on. What is this switch called and where is it located?

It is called a low pressure switch and is located on the line near the firewall. There will be a large tank type piece with two lines and one will be passing through the firewall and the other will run through the engine cavity. The low pressure switch will be attached to one of these lines. Make sure you have freon in the system first. The switch may just be doing its job and you may have a leak. Hope this Helps. Good luck.
