Blower Motor Resistor / Final Stage Unit N2 Location:

Zoom and Print Options

3 things needs checking

1- blower motor resistor

2- blower motor

3-blower motor relay

I have sent you location on all of them

i will send you in a few where to buy, but make sure the relay is not getting stuck so pull it out and clean the contacts

the blower motor resistor or the relay is most likely here ,since blower works good when it does u said

website to buy parts : germanauotparts.com or EBAY is good place
