Nissan quest 2005 SE rear blower motor heat is in high speed i put a new resistor and still same problem

SOURCE: Heater fan only works on high speed 4.

sounds like the switch is bad. Test the power coming in to the connector and use jumpers to get the fan to operate at all 4 speeds. if it works then it the switch.

I had the same thing happen today except rear control works period (no conditions). I am going to test the leads to the front blower first while on. If voltage is there, then I will check the motor brushes - could be a cheap easy fix (~$6 + time). Alternatively you could replace the motor ($50+ plus time). If no voltage there then it is probably electronics.

It could be a resistor(s) but I believe it is unlikely that *all* the resistors would go at the same time.

SOURCE: blower motor does not operate, front defrosters not blowin

1. Disconnect and isolate the negative battery cable.
2. Remove the glove box from the instrument panel
3. Disconnect the two wire harness connectors from the front blower motor resistor.
4. Remove the two screws that secure the front blower motor resistor to the front HVAC housing and remove the resistor.

THERE'S A SENSOR UNDER THE PASSENGER SIDE OF THE CAR UNDER THE GLOVE COMPARTMENT YOU HAVE TO LOOK WAY UNDER JUST LAY DOWN ON TOP OF THE MATT IN FRONT OF THE PASS SEAT IT HAS 2 SCREWS ON IT UNPLUG IT THEN UNSCREW IT TAKE IT TO THE DEALER IT COST ME ABOUT 30 TO 50 DOLLARS BUT THAT WAS THE PROBLEM I HAD. GOOD LUCK

more than likely yes the resistor
