thanks for the speedy reply Steve. If you are refering to the main flap(Ibelieve you are) behind the glove compartment - I pulled those actuators out a while back to inspect them. they seem to work OK and so does the flap - the recirculation switch on the center console sometimes cuts out (I cleaned the contacts,like many of the threads suggest, but it still does that intermittently - I should probably replace the switch).
You do not think then that I should evacuate the system and recharge it ?

Also , any thought about the passanger vent pushing hot air? that seems like a mystery. The first tech I had spoken to said recharging the A/C would take care of that - the second said it had nothing to do with anything of the sort.
