Sounds like the rear blower motor is acting up. It could be a blower resistor/blower motor or wiring connections. The rear paneling will have to be disassembled for inspection and testing of the blower motor assembly. When it doesn't work, you can try hitting the paneling with your fist in the area of the blower motor to see if it will come back on.
I know where the blower motor is for the front of the car, but not for the back of the car. And I cannot find anywhere online that shows me where it is. Also, the back AC doesn't work at all right now. And I noticed that if its the resistor going bad, it should work while it is on high. Any thoughts / suggestions?
I need year make and model to tell you where it is exactly. You are right, high speed is the only speed non-resisted. Sounds as if it may be a defective blower motor
Sorry, didn't notice the info you supplied regarding the vehicle. Hope this helps
This is more info than I've been able to find. I'll check it out and let you know. Thank you!
