The Dealership refers to the resistor as a power unit (for auto climate control) systems. When this fails, the blower motor will not work. No heat or A/C. A different resistor is required for manual climate systems. To access this unit, you will need to remove the the glove box , the support bracket for S.R.S (passenger side) , and possibly the wire harness. There should be left of the blower motor, the resistor. New up to $300. salvage yard $6-25. Try Crazy rays
where the relay for rear blower in Nissan quest 1997
The Heater/Blower Relay is on the blower motor housing under the dash in the passenger compartment on 1999-2002 models
The Heater Blower Relay on a 1993 Ford Explorer is located in the Power Distribution Box. The PDB is in the engine compartment, mounted on a bracket attached to the right fender apron. The Heater Blower Relay is one of six relays, the first relay on the upper left.
Not sure about the relay, but there is a blower resistor assembly located on the heater case to the right of the blower motor.
Not sure, but a 2000 CJ5 blower relay is behind the glove box, down and to the right.
In a 1997 Jeep Wrangler, the relay switch for the heater blower and motor is located behind the dash. It will be directly behind the HVAC knobs behind the dashboard.
Up under dash, passenger side. My mechanic described it as "take a blower, build a Volvo around it". I paid abt $800 several years ago at a non-dealer Volvo shop. Process starts with taking inside of glove box out - you can see it from there...
The only relay in the heater system would be for the high speed function of the blower motor. That rely would be located under the hood, on the firewall, close to the blower motor resistor.
Check your fuses. There is a separate fuse for high speed.
Go To Your Underhood Fuse/Relay Center Located Near The Master Cylinder. You Will Find The Relay There.
you will find it in the heater box, also where the blower is. it is easy to remove.
There is none - usually it is the module in the top of the heater / blower box (resistor module) that is the problem.
