I'm trying to find the dash A/C port on my 2003 Marquis Sapphire?  Anybody know?

John
my 2004 marquis low side port is on the drivers side firewall the only way I could get to it was stand up facing the passenger firewall and reach over the generator housing. My coach didn't have a high side.

John,
Most of the 2003 Marquis coaches had their A/C service valves located between the front cap and the firewall, above the generator opening and to the driver's side.

Is there a way to get the the low pressure port from the generator side or do you need to access through the dash. I found the high pressure port above the generator slightly toward the passenger side

John,
The low pressure port is located in the same area. The service ports are never accessed through the dash on any Beaver that I have ever seen.

The first time I had the air serviced on my 03 marquis the service tech added a set of ports in the engine compartment at the compressor.  It only took him a couple of minutes and did not cost much.  The ones in the front are difficult to get to if you can find out where they are.
