EVAPORATOR VALVE location ON PONTIAC MONTANA 2003 in detail

It is not evaporator (evaporator is a part in an AC system) it is the fuel evaporation control system. It is located under the car near the gas tank.

I don't know if this is what you need? The top picture is evap lines in engine compartment. As far as vac switch, check your local parts store. Talk to the service department at your local dealership. You could try looking up the part at
rockauto.com on the internet. All I did was look up info in my database. I can't see anything from here. Hope it helps.

the expansion valve (TX valve) is located at the inlet side pipe of the evaporator under the dash

where the transmission mounts to the motor, 2003 pontiac montana starter location Bing images

Hi there:
Potential Causes could be the Evaporative Emission (EVAP) Purge Solenoid, fail on Powertrain Control Module (PCM) or damage wiring harness.

Thank you for using FixYa, have a nice day.

The combination valve,You have a proportional valve,this adjust pressure to the front and rear,as for the combination valve it uses the ABS modulator.

There are two possible causes. First is a leaking lip seal causing the system to slip, which the computer sees and it, the computer then increases the pressure to accomodate the slip, causing the bang. The second is a problem with the valve body. Either a binding valve or pressure regulator.

Both of these will require the transmission to be removed to check.

Hope helps.

Usually underneath the dashboard on passenger side, there u could locate a evaporator housing, under that housing there is some rubber hose where water from condensation pass though, follow those hoses till it goes through under the your vehicle!

the battery will be on the passenger side front of the engine compartment. It is under the fuse block and cross bar.
