I've searched through the forums looking for info on how to solve my issue but nothing I have found has helped. I'm hoping that you guys might be able to.

So after an afternoon out on some rough trails, my soobs vent doors to switch from vent to defrost to bi-level have stopped switching, I only have air coming through the main vents. At the same time i also only have speeds 3 and 4, when I have it set to 1 or 2 the blower isn't on whatsoever. I've checked the vacuum lines in the engine bay and directly behind the switches and all seem to be intact. Does anyome have any tips as to where I can search next? Thanks in advance!

The blower speed most likely is the resistor pack has broken. It is mounted in the outlet of the blower housing for cooling. Has a connector with 4 wires.

Did you check that the vac line from the intake to the vac resevior is connected.

 

if so then check above the clutch pedal where the vac line comes into the cab....there is a connection there that can come loose.

Thanks guys, I'll look into those, I would bet that that is my issue. My passenger had hit the blower motor with their foot so it could have hit that as well. Im hoping that will solve the issue.

I think I found the resistor, im going tonorder one and see if it fixes that issue. I did check the vac line near the clutch pedal and it is intact, im stumped as far as that goes. Could the problem be with the vacuum canister itself? It doesn't seem cracked or anything like that, the fuse is good. All other fuses are good as well. Any tips help! Thanks again!

A mightyvac hand powered test vacuum pump will help trace this type of problem.
