We can solve this, but i need more info, a/c compressor should not run with the dash switch to off, so there could be a short in the switch or something is powering your a/c compressor.

another thing is the gas being relieve to your relief valve, your condenser fan could not be running there by creating a high head pressure to relieve on the relief valve or the valve could be open already and not the type where it seats back if the pressure is already low.

are you just putting gas right now as these things happens?

if so, you could have a clogged in your system, building a high head pressure to relieve in the valve.

the clogged could be in the filter dryer, or the expansion valve inside the evaporator coil.

2006 f150 larit a/c works good and periodicallythe compressor cuts out mabey for 15 sec or 30 min

Well, it can be several things. There are high and low pressure cut-off switches. The A/C freon pressure is directly linked to outside air (under hood) temperatures. So if you are at the extreme in either direction, the pressure switches may cut-off.

This is not to eliminate that a pressure switch can be bad. They can usually be replaced without losing Freon. On the other hand, if the Freon system was not sealed, moisture may be icing up and blocking the lines. This can be really bad if the ice forms in the compressor.

As part of a A/C repair a vacuum pump is attached to the Freon lines before refilling. The vacuum pump is run for some time until a vacuum is created and this will draw all moisture out. This will eliminate ice. Then you add the correct compressor oil and quantity and put in the correct amount of Freon. The best amount is usually the makers recommended fill. Maximum cooling happens when the compressor runs the longest and is a balance between the high and low cut-out points.

It sounds like you've done just about everything except to check if there is a bad or intermittent wire causing this or perhaps your low-pressure safety cutout switch is possible going bad causing the compressor to kick on and off?

Compresor dont get current has diagrams for free when you register your car on their site. You can test the low pressure cut-off valve downstream from the evaporator tank by disconnecting the harness from the switch and using a good size wire to loop into the harness.

If the compressor clutch kicks in, you have either low system pressure or a bad low-pressure cut-out switch. This is a test procedure. Even bypassing direct as you have done can risk damaging the compressor.

Besides Freon, compressors need oil, the right type, and a small amount. There are Freon cans which include an oil charge as well as sealers and conditioners to prevent or fix leaks. Remember that the system has a volume limit and more additives leaves less room for the Freon to work good.

If you have low pressure, it is possible that what is left is contaminated. Freon is a gas. Air is a gas. The system was suppose to start with Vacuum negative pressure by using a Vacuum pump(Loaner item). This means that total volume inside your hoses could be wrong. It is easier to understand when you consider the Freon changes back to a liquid and Air needs a much lower temperature to become a liquid. So you lose volume for the Freon to change back from liquid to a gas. It constantly cycles like this to make it transmit heat from the cabin to the outside.

I hope my solution is helpful.

My a/c is not working but the compressor is good. the compressor is not engaging. is there a relay or fuse i need to look for?

No fuse or relay, first if the compressor is not engaging, most times means your system is low on freon. There is a low pressure switch that keeps the compressor safe if not enough freon to run properly. Buy you a can of 134a with a reusable valve/hose and add a little to the system. The valve will have a gage to show if it is low or not. If it is not low, then the pressure switch may be bad.

Need to jump compressor on to recharge refrigerant

You should not have to jump compressor to recharge a/c system, when adding freon low pressure switch will kick compr on, if it's not kicking on or it read low freon on your dash, replace both low pressure switch's, both sit along fire wall from left to right on a thin a/c line, when replacing these switch's make sure what ever freon in system is recover.

The air ride compressor comes on too often

If the compressor is constantly running you have a leak. The leak is either in the line running to the air bag or in the air bag itself. If you're lucky, it's in the line which you can determine if ou trace the lines running from the compressor while its on and listen/look for a leak. The lines run all the way to the air bags which have an electrical relief valve. It's possible the relief valve was damaged when you jacked up the truck as well. If no leak is discovered, then you've got an air bag issue and will need a technician.
Best of luck.

Sometimes there are plugs in the compressor when shipped. Make sure that there is nothing in the compressor where the line attach. How much oil did you put in the system. Compressor are shipped with oil in them. The correct way to measure would be to drain the oil compressor and measure that amount. Then drain the new compressor and compare the amounts. Put NEW oil in the new compressor. Remember the compressor can not compress liquids. It is possible that there is too much oil in the compressor.

AC air is only cool, how do you recharge the compressor?

You can buy a can or,refil kit of R-134-A at walmart however only put the freon in on the low side (read the directions) if the freon gas will not go in; run an 18 gauge wire from the battery to the compressor clutch switch to run the compressor if the freon gas still won't go in it must be evacuated and, recharged by a shop. only put in enough freon to get the system cold any more than that and, you will lose cooling again (over charge)

Air cond dash light works, compressor doesn't go on.

AC's have a low freon switch that shuts off the system to protect the compressor in the advent that you have a freon leak have the system checked for a leak
