Re: Passenger Kkck panel fresh air vents

If your vacum lines are still hooked up slide the top lever on your a/c control panel all the way left with the engine running. The vacum actuator on the kick panel vent should open it, the one on the firewall should close the flapper in the cowl and the heater valve should close on the heater hoses. and if the lines arent hooked up or if your truck is disassembled just put on a small peace of vacum hose on it and suck on it to get it to retract. I then usally put my finger over the end of the hose and wait a couple of minuts to see if the thing returns to its original position, which would indicate a leak. That is how I test them to make sure they dont leak and work
