Re: Blower motor stays on
FFShawn,
Always helps to fully state all facts. I see endless run-arounds on the sites I frequent from people assuming others know what they mean by some brief statement.
I think the fan will draw more than normal current only if it slows way down (bad bearings, dragging cage). When the motor spins fast (your problem), it generates "back emf" that reduces the current draw. You can read up on wikipedia and such. Hopefully, you can return the failed modules, though some stores don't warrant electrical parts.
The easiest way to test a relay is to just swap them and see if the problem follows the relay. You need a wiring diagram to locate the correct one unless they are labelled (engine bay box ones are). I think it unlikely that a relay is the problem. That is just a power feed to the whole climate system and maybe other things. Measure with a multimeter to see if you are getting the full battery voltage. In new cars, you usually must stick a pin in a wire to probe since the connectors are all sealed.
