AC/heat not blowing

Welcome to 2CarPros.

Does it work on any speed? If not, the first thing I would check is the blower motor relay. It is located on the left side under the dash. I attached a picture of the relay and the location.

If you find a relay with the same part number, switch them. If you don't, here is a link that shows how to check a relay:

Here are a few links you may find helpful when testing:

Let me know what you find or if you have other questions. If the fan still works on the high setting only, let me know.

Take care,
Joe

Not the relay. Not the fuses and not the resistor. Mechanic did not know why was working and just quit. Could it be control panel?

Welcome back:

It could, but to confirm it I would be checking the things I mentioned first. If they all pass, then he will have to check the control panel. It could even be a bad or weak ground.

Let me know if I can help.
