Weak glowing air bag warning light, ABS light, about to stall engine, and blower not engaging until the speed is turned up all the way. These are the weirdnesses that I encountered over the last month on my 2003 V8 EB.
I traced it down to the blower motor speed selection. When the vehicle has been standing in the cold the blower will not blow instead a sound can be heard. It's like a pneumatic switch tries to do something but doesn't get it done. Is there by any chance any pneumatic stuff with the heating vents? Anyway, while this happens the air bag light glows weakly. When I turn the heater off or turn the fan to max then the airbag light is off. Once the blower was on max speed it works on any speed. Also the blower works fine if the Explorer has been in the garage or is still warm from a recent trip.
Could my problem be a bad blower motor having a short or near short and draning all the electrical power from the other systems? I read about the blower resistor but I doubt that's the problem since the blower works fine under certain conditions.
What do you think. Is it the blower motor and should I replace it? Or is it a shot in the dark and the blower replacement may just be a waste of money?
