No ac no heat

[bethvaughn]

HELP! My son’s AC/Heat won’t come on at all. He’s replaced blower motor, all fuses that go to AC and replaced the resistor. Still NOTHING! This happened after he went mudding. Anyone know what’s going on?

Is the motor running at all?

This happened after he went mudding.

One of the vents could just be plugged. Given the work done I assume you have checked the filter?

Just stirring the grey matter up.

Isn't the Body Control Module some where are the front drivers side tire ?

If that was buried in soupy mud, would that be the cause of the HVAC system losing power ?

Maybe expose the BCM & clean it up a bit & give it a good look over
===============================

Looks like early 3rd Gens, have a Sealed Forward Control Module, it is mounted up on the side of the fuse box

so i think that my guess was wrong
