Both front and rear blower motors quit working

 

Check you owner manual for fuse location, both blowers out , probably fuse

 

Fuse and relays are okay. One day they will work, then the next day they wont.

 

So a change in reported behavior !

 

Can the relay on one motor affect the other motor?

 

I meant resistor, can one affect the other blower

 

NO!, dont start firing parts before testing..

 

I agree that one motor doesn't effect the other one as they are on different circuits but thats what a mechanic is trying to tell me. Just seems odd that both would fail at the same time but the main fuse feeding both is good.

 

Do you have a test light (preferred) or meter ?

 

Yes I have a meter.
