There's an access panel underneath the glove compartment and I'm tapping unit it works sometimes but now it's getting worse

It seems like when I hit bumps it comes in and out


I think you may need a new blower motor.

Im hoping its a lose wire or something..thanks for...your response.. worst case scenario I go get another heater and install it watching a YouTube video


Check the wires to the fan motor and to the resistor.
