Heater Core or Blend Door...Which one?
A few months ago I observed when the A/C on, hot air would blow out of one side of my vents and cold air from the other side. This happened only occasionally.
Now, not being new to this forum and after doing much reading I determined that my jeep is just another victim of the broken blend door problem. Simple enough to fix. Planned on doing the repair myself (without dash removal) over my upcoming vacation. But now something else has me puzzled.
Just this past week, after about five minutes of driving, my glass completely fogs up. Heavy fog pours out of the vents, and the A/C and fan control seem to not respond at all. This happens every time I drive it now. I do detect the slight, sweet smell of anti-freeze. No leakage in the floorboard.
So back to the forum I go and decide that my Jeep is now showing symptoms of a bad heater core. BUT, I am wondering if the fogging problem could be a symptom of the blend door issue, or is it just a weird coincidence that BOTH things go bad at nearly the same time. I couldn't find any posts here with anyone complaining about both issues at once.
Just wondering if I should even bother with doing blend door, without dash removal and see if it works OR man up and pull the dash and replace the doors AND the core. Trying to save time and especially money. Many thanks!
