Ok so I'm pretty sure I know why the a/c fan/blower quit

Customer Question
working. The heater control valve...
Ok so I'm pretty sure I know why the a/c fan/blower quit working. The heater control valve that I replaced about 2 yrs ago split right down the middle and antifreeze sprayed all over where the blower motor is located. My question is how do I know what is bad? Is it the harness corroded, is the fan fried, not sure what a resister is but could that be fried? Another words I need to help to trouble shoot so I know what to replace.

hi, first check to see if you have power and ground to the blower motor .

if you do then the blower motor is bad .

if you don't then it is time to check your fuses and check all of them (I say this because that is what I do and you may find fuses blown that you didn't know about )

Next check the blower motor resister .

you can take this out and test across all the terminals with an ohm meter

any one should show continuity when you test the terminals ,that is if you put one test lead to any terminal any other one you put the other test lead should show continuity ....

as a hint it usually will be a fuse or blower resister ,and sometimes the blower motor ...jazzmaster ..

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
