I can't get my heater to recirculate the cabin air. Every time I push the button it flashes three times. What is wrong?

Max Power 02-26-2010, 06:26 PM It has to be above freezing outside to be able to use recirc. IIRC. theunderlord 02-26-2010, 06:26 PM what vent setting do you have it on? (like head/feet/defrost/both) tommystunes 02-26-2010, 06:30 PM I think it only works with ac on mike207 02-26-2010, 06:32 PM I tried it on a bunch of different settings, maybe not ac though. Tanc Crusher 02-26-2010, 06:41 PM The recirculate for me will not work if vent is set to feet only. If any other like deforst or front vent or combination the recirculate will function with or without AC on. And it was 20 degrees the other day doing that. I normally would not run long since it can start to fog up the windsheild after a period of time. Just do it to maybe heat the cab faster so it does not have to heat in coming outside air and the cabin air in normal mode. Brian theunderlord 02-26-2010, 06:50 PM The recirculate for me will not work if vent is set to feet only. Brian same here. mike207 02-26-2010, 06:52 PM Hmmm. Something strange is going in here. Mine doesn't work at all. Tanc Crusher 02-26-2010, 06:58 PM This is way out there but a thought. Do you have elevated idle? I seen threads that mention in colder areas that the elevated idle is disabled. So that is tuning in the BCM but do not know if they modify anything else. Brian mike207 02-26-2010, 07:00 PM I have elevated idle, and its usually turned off. Tanc Crusher 02-26-2010, 07:12 PM Ok just wanted to eliminate the one change I heard of in cold climate. You got me. I guess one would have the service dept reprogram the HVAC module. That probably be a charge unless they do a diagnostic and if there is a warranty. Brian Camp I am 02-26-2010, 07:17 PM Mines doing the same thing. My thoughts are it's too cold outside. I'll test more when it gets over 30 degrees in a month or so. :cool: | ||
