Default L300 blower control module

We just bought an 03 L300 with climate control (c68).

Often the blower will not work without banging on the passenger side of the climate control housing.

I bought a replacement 'blower control module' but I'm not sure where it is located.

I'm assuming it's right by the control/head unit for HVAC?

I also have a new resistor card, just in case.

Any advice is appreciate!!!

Brad

REWARD EXCELLENCE!

Default Re: L300 blower control module

If I'm not mistaken, the blower control module is the resistor card. The terms are interchangeable for the same part - a solid state module to control blower speeds as commanded by the hvac control head in the center console. Access to replacing the module is after removing the glove box with the bcm sitting on top of the plastic glove box. I replaced the blower control module too when blower speeds were lost. I checked fuses to be sure none were blown before wiring diagrams led me to the blower control module. The glove box cover is removed then the glove box is slipped out or slipped further into the compartment to reveal the bcm clipped to the top. The bcm fits into a slot, released from inside the box to slide the bcm off the plastic compartment before it can be removed completely. Once removed, you can see the blower control module on the right side of the hvac box. Search for my thread about it.
