i have a 97 TJ and its been getting real cold the last few days here in NYC, so I turned on the heat. Here's what happens...
The first two settings seem to be identical. The car blows warm air (at best) and barely enough just so you know that it is on. And its the SAME speed and heat on the first two levels. Then I turn it upto the 3rd and 4th setting and it does blow better but the air is still just lukewarm. Not hot at all. This is pretty much the SAME throughout all the went with the excpeption of the leg option where it barely blows at all.
I have to drive FULLY dressed in gloves and everything otherwise its real cold in the TJ.
What can this be?
Can it possibly a vacuum leak somewhere?
***The reason im thinking maybe vacuum leak is because along-side this issue, the wrangler doesnt idle 100% steady. I cant figure out what it is AT ALL and Ive been at it for some time now, did plugs, wires, cap, rotor, sea-foam cleaned the IAC, seafoamed it, replaced the CPS. No CEL, but no improvement really.
Maybe its just how the 2.5L idle but I feel like that cant be the case. It almost has surging idle. It will be steady for 3 to 5 secs then surge up 50-100 rpms then back down, then again and again....and it sort of takes a while for it to turn over. It cranks well but it cranks 5-6 times on average before it turns over.
Im sorry for the never ending post but I wanted to provide as many details as possible to narrow down the problem.
THANK YOU SO MUCH for any & all of your input!
