First, I would like to thank you for helping, I've used your forum to resolve other car issues from your prior posts. It's nice to know where to find web help a person can trust.

Second I have two questions:

1 - Blower motor will not operate on high, all other speeds work. Checked fuses, swapped relays, now I'm stumped. I have volt/ohm meter (and know how to use it). Need wiring diagram if possible.

2 - Engine idles at 1400-1800 RPM in park or neutral, while in gear the engine will eventually start to chug. Have SES light on but cannot read code because code reader could not communicate with computer. I was told, "most likely power to the OBD connector is missing" and to "check the fuses". All fuses good and cannot figure where the power comes in. Again a wiring diagram of the OBD circuit would be helpful.
