  • 1999 Chevrolet Tahoe

I have a 99 Tahoe that will not switch between defrost, vent, floor, ect. It will blow heat and A/C but will not allow me to switch between the various outputs.

Thanks for any help, it's appreciated.

Sounds like you have a broken vacuum line somewhere under the hood. Usually goes through the firwall near the a/c accumulator

Awesome, can you point me in the general direction of where the A/C accumulator would reside?
