AnswerOK,
1. turn the ignition key ON.
2. Set the control to full heat.
3. Put the blower switch on HIGH.
4. disconnect the 2 wire electrical plug at the blower motor.
5. Using a standard 12 volt test light, attach the alligator clip of the tset light to a suitable metal ground and check for battery voltage at the wiring harness BLACK connector for the blower motor at the DARK GREEN wire.
Do you have battery voltage ?.
If you DO have battery voltage, Proceed below.
1. Remove the test light alligator clip from your ground source.
2. Attach the alligator clip to one of the terminals in the wiring harneess portion of the blower motor BLACK electrical connector and insert the TIP of the test ligh into the other terminal and se if the test light glows at different intensities as you move the blower switch from LOW thru HIGH.
Does it glow at all ?.
Question: has anyone removed the small plastic kick panel that would be right next to the passengers right foot if they were seated in the vehicle ?. As there is a large BLACK ground wire located and attached to the metal brace behind this kick panel and if it is loose or broken OFF you will have no blower operation.
Check it.
let me know.
