I have a 99 Grand Prix GTP with climate control. It had the problem where the water was dripping onto the passenger floor through the blower motor. The drain plug in the engine bay was clogged and when it rained it just dripped into the cab. And the rain diverter at the top of the hood, just under the windshield, was pouring the rain into the fan/blower. Anyways, I replaced that plastic piece so it no longer drips into the blower, and I unclogged the drain plug.
The blower worked at that point, but now it doesn't work. I looked all over forums, it doesn't blow at all, not on high, not on low, not at all. I checked the blower and there is current going in and coming out. I checked the resistor and it was junk so I replaced it. It did not fix the problem. I checked the head unit connection and it looks great (no fried wires). I checked how many volts were going to the blower and it was real low, like 1 volt when it requires 7. So I replaced the head unit, still did not fix the problem. I am stumped at this point.
Can anyone help me figure this out before I bring it to a mechanic? Kinda need heat for this below zero weather we are having in mass. This weekend it will be 50 so I'd like to have a last attempt.
Thanks
