Heater problems

So heater won't work well no air will blow out have switched out both switches there was no melting all the fuses are good so I'm guessing the last thing could be the blower motor does anyone have a link of how to replace one ? Or any other things I can try maybe something came loose?

Jump 12V to the blower motor to see if it will run. If it does, check for 12V at the plug when fan switch is turned on.
If both are OK check the plug at the blower motor. Make sure the contacts are clean, tight and make sure you have a good ground at the plug.
Hope this helps.

You would remove the plug off the blower motor, take a test lead or piece of wire, attach one end to the positive battery terminal, and touch the other end to the blower motor terminal. Most likely you'll hear a snap, don't drop the wire. But after the snap you should hear the blower motor running.

Sounds like you have the correct plug. To make sure you should also see the motor and mounting screws for the blower motor on the firewall.

The plug is a tight fit and difficult to remove but if you are considering replacing the motor then obviously you have to disconnect the plug so go for it.

You might try wiggling the plug to see if anything changes like blower operating normally or just comes on randomly.

I forgot to mention that if this is your blower motor placement you have to remove the control module that is on the firewall for better access and the battery if necessary.
