MY A/C IS COMPLETELY OUT OF COOLANT(01 F-150), HOW CAN I GET THE COMPRESSOR TO KICK ON TO TAKE A CHARGE?

 

Pass side just below the battery there you'll see a switch attached to the high side line of the A/C...pull the connector and short across the the connector with a paper clip...compresser will come on and start charging fast...do not hold the can upside down...if you want a quick charge put the can in a can of hot water as soon as you start charging but make sure you remove it as you get close to slow the charge so you won't over charge...run the a/c on max fan on high..rpm around 1500.....and put a high volume fan in front of the condensor coil to force air through it....take your time and place a temp gauge in one of the center dash vents so you can see the drop in temp...it would seem that you have a leak...it could be in 3 places....there at that cut off switch...at the condensing coil (Lotcus can pierce a tube but most likely a rock)...or the seal on the compressor shaft behind the clutch

 

TRIED TO SHORT ACROSS SWITCH BUT COMPRESSOR WOULD NOT KICK ON, ANY MORE SUGGESTIONS?

 

check for blown fuse!

 

Not the switch ...the connector...yep check for a blown fuse...check the connection at the compressor clutch itself...is it loose or full of dirt?
