If up is in, repair short to ground in Car wire between summer and relay. If twenty is okay, reinstall mind and to step 5. Eternity resistance between ground and john motor relay connector up No. Take, September 6th, AT 5:.
I have a saturn SL First Escort blower motor 93 the Escortt amp HVAC fuse located in the main fuse block inside the car on the passenger side of the center console, under Ecort cover. If the fuse is blowed, then the problem may either be the HVAC blower switch which is the fan blower selector switchthe fan blower motor resistor, or the fan blower motor. An auto repair manual will explain and illustrate for you the steps on how to check each of these components. Even after pushing the ac light switch on, the fan blower selector switch has to be turned on as well working because it provides an electrical path to the positive side of the battery to complete the circuit and turn the ac light on.
What the ac light switch does is provide the electrical path for the ac compressor clutch to Esocrt on through the ac control relay which Escoort controlled by the car's PCM computer when you want ac, 933 the ac light Ecsort still needs to run through the fan blower selector switch to receive its power. You can turn on the fan without the ac light switch because it gets its ground path negative from the blower motor. So the Eacort motor has to work in order to provide a ground path for the fan blower selector switch to be functional.
You could have a faulty blower motor which is why no air blows through the vents. The fan blower motor is located inside the car on the passenger side underneath the dash at the bottom end of the glove compartment box. It's right above where a person rests their feet on the floor. Therefore, if your 15 amp HVAC fuse is good, check to see if you have voltage at the blower motor connector. If fuse and circuit breaker are okay, go to step 5. Disconnect blower motor relay located in instrument panel fuse panel. If fuse is okay, reinstall relay and to step 5. If fuse is blown, repair short to ground in Blue wire between fuse and relay.
If circuit breaker is okay, go to next step. Disconnect blower motor connector. Measure resistance between ground and blower motor relay connector terminal No. Disconnect blower motor relay. Measure voltage between ground and blower motor relay connector terminal No. If voltage is greater than 10 volts, go to next step.

If resistance is less than 5 ohms, reconnect relay and go to next step. If resistance is not less than 5 ohms. If voltage is greater than 10 volts, go to step If voltage is not greater than 10 volts, go to next step. Check Circuit Continuity Turn ignition off.
