Hello. Thanks in advance for your help.

I’m having issues with my HVAC. Sometimes it works, sometimes it doesn’t. That said, oftentimes if I hit a speed bump it will start working again. Maybe something loose? I do not know.
Please help

Good afternoon,

It sounds like a bad connection at the blower or the resistor itself.

The blower motor s behind the glove box. I would check the connector at the blower motor.

I attached some pictures and a wiring diagram.

Okay, I finally got under the dash and unplugged the resistor. It doesn't appear burnt, but I'm unsure as to how it's supposed to look. Haha.. Should I go ahead and replace it?

Did you check for voltage to the resistor?
