Blow Motor Resistor Board

[vmodi]

Took my 98 Pathfinder to the local mechanic who diagnosed that my blow motor resistor board is gone. I get no air at auto, I, II, or III setting. The blow motor worked fine when connected as-is to a car battery.

 

What is a good place to get the resistor board? Is this something I can replace myself? Any place I can see the step by step guide to it?

 

Thanks!

Not sure on R50, but on WD21, you remove the glove box and the resistor is right there in the air exchanger housing. The one in the WD21 is about $36 from the dealer, again, not sure if they used the same one.

Compare that with your local dealer prices.

This is an automatic AC system so it uses a variable blower power control module in place of a resistance unit.

All R50 pathys use P/N 27761-70T03. List is $156.46. I can get it for you at $102.08 if you need it.

 

 

 

 

I have also seen, albeit rarely, that the AC Control Amplifier (basically the brain of the Auto AC system) has gone bad and gives the symptoms of the Power Module being bad. Again very rarely, pray it is not so!

 

I would also recommend cleaning the duct from the In Cabin Temp Sensor to the control module. This tube clogs up with dust bunnies easily and gives bad input to the AC system causing the system to run harder or not cool as well.

Thanks everyone!

 

I am moving to San Jose, once I have a shipping address will definitely need the variable motor board. Didn't know it would be ~$100 but better than ~$150.
