Hi all,
first post after returning to the TJ club after a 15 year hiatus - picked up a 2005 TJ SE (with the 4L) and will have a list of to-do's for it. Right now as winter settles in, what is getting me most is diagnosing the HVAC issue that seems to hit plenty others where I am only getting defrost blowing.
I've traced all of the vacuum line and seems intact, in fact it looks like it was recently replaced before purchasing as it's near spotless. On the HVAC control panel, the fan levels all work (off, low, medium, high) as does the temperature. The location of the blowers does not other than OFF. I can turn it off, but any other option goes just to defrost. I've poked around under the dash and seems all the control arms are OKAY (one is easily accessible under the drivers side dash, one is not - and one is semi accessible behind the glovebox). The HVAC control panel is marked as '00 Wrangler so seems that was replaced already before - but am wondering if because it does go off to just on, is it the control module there or something else? Where do I try and troubleshoot next without ordering a bunch of parts and pulling the dash off? To add to my semi confusion, RockAuto lists 55037612AA as one option to order (which has the long vacuum lines that are needed), and I can find what seems to be an equivalent on Amazon which the listing shows is a replacement part, but only lists '99s-'04s. Free returns so might try.
Any suggestions for trying to better trace next possible root problems?
Thank you
