You can test for power with the test light but to check for a ground with it you would need to hook the aligator to a power source on the cars electrical system. Turn the blower on high with the key in the run position. Then wiggle the plug at the blower motor see if it starts working. Also smack the blower motor with your hand see if it starts working. Also unplug the blower motor and see if ethier terminal looks open. Check and see if your getting power to the blower motor. You should invest in a multimeter there cheap and have a lot of uses. Let me know what you find.

Yes the blower is bad it was making a clicking noise last winter and I could smack it and it would some what stop the noise but it was still making the noise just not as loud like something was in it kinda like a playing card being put into a fan like we use to do as kids to make it have that clicking sound but shouldn't it still put out heat? Just not with force by the blower? It should still get warm right? If it should still get warm well its not doing nothing it wont even get cold

It uses the blower motor to blow air across the heater core for heat and blow it into the cabin of the car. Also the blower blows air across the evaporator for cold air into the cabin. No air no heat or cold its not like those radiators they use in homes to make radante heat. Both the heater core and the evaporator core are deep in the dash and need the blower motor to get the heated or cooled air out. Lets start with getting blower motor working and see how the coldand hot air works. You can test it like I explained earlier.

It all depends on where you buy it if you shop around you will save money. If you buy it online verus locally it will probably be cheaper. Online I would try amazon and www. Rockauto. Com I have a 5 percent discount code for rock auto I will share with you if you need it.
