new blower resistor,switch,and a/c selector switch -
Answer 1
HI SPEED DOESEN'T GO THROUGH RESISTOR. LOWER SPEEDS DO.CHECK RELAYS AND FUSES AGAIN. THEN CHECK THEM AGAIN. DOES AC SYSTEM HAVE FULL CHARGE? ALSO CHECK FOR OPEN FUSE LINK NEAR BATTWEY. -
Comment 1
yes a/c system is fully charged, swapped out a/c relay, and if i jump the low pressure switch the compressor should come on but it doesnt. -
Comment 2
Does it have hi speed blower relay? Is 12V present at press. switch and comp.coil? Poss.two problems,field coil at compressor and open circuit to hi. blower. Just saying, good luck. Still suspect fuse link. -
Comment 3

Comment 4
