HiBeen playing around with the airconditioning on my truck (as it blows hot air and has done ever since I got it -> but its not been warm enough for me to get on it).Figuring it was low R134a or whatever - got the walmart kit and started filling - problem was it would only allow like 10% of the can to be dumped into the low pressure port/accumulator before it was complaining of too highpressure on the guage. Well I couldn;'t hear the compressor - so after reading around I figured that was it.I climbed under and diconnected the sensor/wiring harness.I then tried to use a piece of wire to bridge the wiring harness - it smoked a little - then nothing.I got my multimeter out and it says no signal. (But I'm figuring there had to be a signal to cause the wire to smoke) ?? So - did I burn something ? More importantnly - have these 2 basic questions 1) How do I run a jumper wire (which I guess needs a 12V supply) to the sensor for the a/c compressor to get it to turn on ? Simply Using a paper clip etc on the sensor end won;t work as their is no power right ? Do I need just 1 wire from the +ve terminal of battery or do I need 2 wires (1 +ve and 1 -ve _ to complete the circuit ?? 2) How do I tell if the wiring harness is burnt or having an issue ? I stick my multimeter in the two connectors - but get 0 signal. Could it be a fuse - which fuse - in cab ? left side of truck where my edge juice is sitting on - or somewhere else in a relay ? Trying to work out if A/C compressor is dead or wiring harness is dead - or fuse - and how to force a 12V signal to the A/C clutch/drive compressor to get it to start circulating so I can fill up with the R134a refrigerant hope that makes sense gonna go get a pic now ......
