Like most of us 2nd Gen Charger owners there comes a time when the vac operated doors don't work properly. Mine go up but will not go down.
I am now replacing every vac hose and just found a repop vac canister which should be here in a few days. Has any one tried this to test the vac actuators to ensure they are working? Would using a brake bleeder tool work? The type one person can use to bleed a brake system? It may pull enough vac to test the actuators, I hope. I could also try using the vac line off a running car and hook that directly to the actuator but I don't want to chance damaging the actuator. If I do all this then my last resort is a new switch in the dash
