My a/c and heater both won't work so I assume my blower motor is bad can I teat it inside the vehicle or do I need to remove it to test it?

 

If you can feel a bit of heat from the floor vents when you switch the setting to heat, and you may even feel a little cool air in the dash vents if you switch to A/C, but it's not actually blowing the air, then yes, something is wrong with the blower motor. Be sure to check all fuses and relays before you replace it, just to make sure it's not something easier to replace.

 

Where is the relay located?

 

I'm not entirely sure, you might wanna check out this site though, it looks pretty useful.

It is very useful thanks. Now if I could only read it correctly lol

 

take a couple wires and unhook your blower motor under the hood and run two wires one to your possitve on your battery and one on you negative and touch the connector with the other end of the wires it should kick on
