Heater/ AC Blower help...

[msd44]

Sorry for the newbie questions, but I am in need of some help.
It seems that the blower unit on my 2003 4runner is on the way out. If I go to turn on the heat or AC, the head unit works as it should, but I get no airflow out of the vents. I pulled out the glove box, and check the cabin filter it see if it was clogged... no issues. If I just touch the fan blades in the system, it spins and all is good. It will work fine for a few days, but the same issue. At times, if I hit a large bump in the road, it turns on by it's self with out assist from me.

Is it time for a new blower unit? Or is there something that I can do to fix this problem?
Any help is greatly appreciated. :thumb3:.

Hey msd44,

You don't indicate your location, but if you are in a cold weather region that has snow and ice this winter, check out this TSB on ice build-up on the HVAC blower motor.

This happened on my wife's 2003 V8 Sport Edition. Turned out to be the resistor unit. Cost a decent piece of coin.

Order one from Conicelli's or something. Dont pay the dealer price. Sucks.
