guess my other post didnt go through. why is the plug bridged like that? is that good or bad for the car?


thanks

 

That's to keep the AC running when the Freon is low. Either that, or the switch has failed.

 

Like the five7kid said, that is jumpering the low pressure cut-out switch for the air conditioning compressor. The only time you want that on is when you are putting the initial can or two of freon in the system when there is no freon (or pressure) in the system.

You shouldn't leave that hooked up permanently. If there is a bad switch replace it. Otherwise if your system gets low on freon, it will not circulate enough oil to the compressor and you will end up ruining it.

 

alright thanks guys ill hook it back up. plus how do i know if the switch is bad?

 

you definitely dont wanna leave it like that... compressors arent cheap and you dont know they are bad until you fill em full of freon

 

like mentioned you only jump like that when the freon is low during recharge, running it like it is will cause damage. Pull it off right away.

 

Hook up a pressure gauge. If the pressure is high enough and the switch is open, the switch is bad.

I don't know the proper pressure off the top of my head.

 

IIRC it should be around 35lbs on the low side but only 150lbs on the high side IIRC .
