Nissan Repair: 88 pathfinder heater blower isnt cutting on, blower motor resistor, heater blower

Question
Hi there. I am having a problem with my heater blower in my 88 pathfinder not
working at any speed. For a long time it only worked on 1-3 speeds, but now it
won't work on any. I have replaced the blower motor resistor, but it didn't fix the
problem. Do you think that the heater/ac switch assembly could be causing the
problem? Thanks for your help!

Answer
Matt,

If the blower does not work on any speed I would check the blower motor rather than the switch.  Remove the cover under the passenger side of the dash and check the power cables to see if there is power to the blower motor.  All you need is a test light.  If you have power replace the blower and if you do not check the switch you were talking about.
