The recirculate button for the HVAC isn't working, leaving me to inhale exhaust from poorly maintained cars in front of me. I'm at a loss to figure if this is a mechanical problem or electrical. Any advice out there?
Turn on ignition, after 2 sec press OFF for 5 sec. System goes to mode1 - indications check
mode2 - sensors check - press increase temp red button
20 OK
21 Ambient sensor
22 In vehicle sensor
23 Termal transmitter
24 Intake sensor
25 Sunload sensor (to check sensor should be lighted by sun or 60W light bulb)
