In preparation for summer, I would like to tackle an ongoing issue. I get the dreaded a/c book on the screen every time I hit the recirculate button.... and every time the auto function tries to engage the recirculating button. I prefer the recirculated air. Is there an easy way to force the vents to recirculate the air? I am guessing that my reciruclating servo is bound up in the open position. Recirculating the air seems to help w/ cooling the air in my other cars so I was just curious... Thank you!

:think: fresh air blend motor? seriously, unless you are behind a dung hauler there is little difference in process. Recirc is great in Phoenix when it is 120 and you want your black rig to cool down. Recirc is great when you are stuck behind Snow White and the seven unshowered dwarfs. the rest of the time I leave my rig on auto and let the system do what it was designed for.

This gives you time to hunt up a set of blend motors, a case of yoru fav libation and a team of buddies to support your cimtinued ownership of a P38 while you rip your entire interior out to fix a tiny little glowing bit on your display.

Since we are on this topic, is there a way that one can completely TURN off the HVAC system. It seems that even when the fan speed is on "0" there is still air circulating. IS there no way to just completely turn off the system, so that the only air coming through is wind being pushed from the outside?

I don't like AC and like to drive with my windows down, temperature set to "cold" (as in outside air) and the fan off....
How does one get the AC to work? By pressing the "ac OFF" button so the light is on or when the light is off?

Hi

To stop the heavac ecu from working completely you just unclip the connector with the power supply.
It is accessable after taking out the radio.
Connector C244 see page 1155 of the workshop manual.

Alternatively you could take out the fuse but it is the same fuse that feeds the radio and cigar lighter.

If you are really serious make a switch in the supply wires of the 12 VDC supply to be able to switch off the power whenever you want. Get a 3 pole switch and disconnect wires 1,2 and 3 of connector C244 simultaniously.
