On this episode of jeep no working. A/c is not blowing at all. Bought new a/c resistor still not work. So bought a fan for it still not working. Then replaced relay behind glove box and checked all fuses . Anyone have any clue. A/c compressor does work. Fell cold air when driving.

when you pulled the old motor out, did you apply 12v directly to the old motor? was it definitely burned out?
if you put a new motor in, did you test for 12v at the motor?
No 12v? start working backwards. keep going until you find 12v in that circuit. Do not start at the blower motor, then jump to the fuses, then to the switch, you'll drive yourself crazy trying to find the break. start at one end, and trace the circuit to the next connection, until you find the break

Just went back and checked the 12v it didn't work so looks like it goes back into the resistor switch through firewall. Then checked the 12v connection on the wires to the resistor no connection either. Going to go back tomorrow and look further thanks for the help
was and HVAC contractor for 30 years, chasing electrical problems, especially intermittent ones, is always a PITA. Good luck.
