I have a 1994 Ford Escort. When I turn on the heater, I notice a drag on the motor and the lights dim a little bit. This happens repeatedly on a cycle, somewhere around 10 seconds. I still get heat, but it's the same kind of feelind like the compressor is kicking in.
Does this sound like a blower motor? Loose ground? Voltage regulator?
I'm really not looking forward to replacing the blower motor if that's what it is. If it's a ground, where should I start looking? If it's the voltage regulator, how do I test it?
Thanks in advance....
