The power is on but motor not running - Cars & Trucks

Have you checked all your fuses ? If they are all good, check power to the fan it self. If no power, you may have a had power wire or maybe a bad resister or motor. Remove harness connector from the motor and check to see if you have power at that end, if yes, then your motor may be bad. To verify motor, just connect power and ground wires directly to the motor, if it runs, you have a wiring problem or bad resister. If it does not run, bad motor.

Can you hear the motor running? If not check the fuse first. If the motor runs but the wipers don't move then the transmission has failed. If the motor isn't running and the fuse is good then the next step would require you check for power at the motor. If there is power (with the switch on) then motor is bad. If no power then probably the switch is bad.

Left Front Power Window Switch
The battery voltage is applied from the WINDOWS circuit breaker through CKT 42 (RED) to the accessory time delay relay. The accessory time delay relay supplies voltage through CKT 70 (PNK) to the left front power window switch under the following conditions:
?€¢
The ignition is in the RUN position.

?€¢
The retained accessory power (RAP) is active.

When an UP switch on the left front power window switch is operated, the battery voltage is applied to the power window motor. The power window motor is grounded through the DOWN contacts of the left front power window switch to G204. The motor runs in order to drive the power window up. When a DOWN switch in the left front power window switch is operated, the battery voltage is applied to the power window motor in the opposite direction. The power window motor is grounded through the UP contacts in the left front power window switch to G204. The motor runs in order to drive the power window down.

if the blower motor is not working and the fuse is good then check for power at the motor with the key on and the fan speed switch on. if you have power at the motor and its not running then check the ground side at the motor if this is good then replace the blower motor. you can also try hitting the motor to see if it will start to run but this does not always work. if you have no power at the motor then it is probably the blower motor resistor that is bad.

Two possibilities:
1. The switches in the A/C system aren't turning it on, or
2. The fan fails to run when it has power due to blown motor.
To test find the motor to the fan and pull the power plug off it and make a fused jumper wire fused to the fuse size in the system test run the motor directly with power from the battery. IF the fan fails to run it is the fan motor, if it runs than, it is the A/C system controls that failed.

85 and 86 are your coil wires. If you are using a standard single pole switch, you can run power to the switch, and back out of the switch to pin 85. Ground Pin 86.

Run main power for the lift motor to pin 30, make sure to fuse this accordingly, no more than a 30amp fuse if this is a standard 30amp SPDT relay.

Run pin 87 to the motor's power input. 87A is not required. This is wiring is just to power the motor in one direction.

more than likely water in dist cap.remove & spray with a electrical cleaner let dry a few min.
checking/clean plug wire contacts @ dist cap, apply dielectric grease to contacts

Not sure exactly what you mean. Do you mean that when you run power to it you can turn the wipers on and off with the switch, or do you mean that the motor just runs when you run the power to it? If you mean that it runs automatically when you run the power to it, I would suspect the switch. If it works with the switch, it sounds like a wiring issue.

make sure fan fuse is good, remove power wire going to blower motor then run a power wire to the blower motor from the battery install a an inline fuse in that wire from battery , if it runs with direct power then may be a resistor or switch, remove direct power wire reconnect orginal power wire to motor turn switch to blower on, use a test light see if you have power at motor with switch on, if theres power then motors no good, hope this helps.

if fuses are good, check for power at blower motor, when truck is running and a/c on. the resistor and the switch provide ground, so the blue/white wire should have power, and the blue/black wire should have NO power, if it does have power, then most likely the resistor is bad. if it has no power and the motor doesnt run, the motor is bad.
