heater sucks!!
This has been the one ongoing problem I have had with my 99 tj that is drivin me insane!
My blower controls work perfectly on all speeds and the duct selector switch works as well, i.e defrost,vents hi n lo, but the problem is, I cant seem to get the damn heater to get "hot" and blow good hot air.I have replaced the blower resister,the fan switch,flushed the engine SEVERAL times,even pulled the heater hoses off and checked circulation by hooking a garden hose to it and checking that it was actually "circulating" through it. Have also replaced the t-stat.Only thing I have NOT done yet is replace the water pump.
Have any of you tj owners been thru this problem? It is a 99 tj sahara,4.0 l w/ac.
Don't the TJs have a seperate valve to control the water going into the heater core? If so it sounds like that may not be opening. It is also a possability that your heater core is plugged, though I would think that flushing would help. When you flushed the engine did you throw the controls to hot?
capitol,
I had the same problem with my wrangler where everything worked but it would not get hot. One of the techs i work with told me to drain the system and either put it on a slight incline(hill) or raise the front end up off the ground just enough to where when you refill it you can get all the air bubbles out. Once you refill it lower it back down, start it up and check the level. The coolant level might go down a little so while it is running top it off and put the cap back on. Let it run enough to bring it up to normal operating range then check your heat again. I hope this works for you, it did for me and my heater works really good now. Good luck.
when you flushed the heater core, did you flush it in reverse of the normal flow? also, when you flushed it, did you put anything in it to loosen the gunk inside? (used microwaved bleach, set for 10 minutes, then flush reverse flow - alot of brown gunk came out). if so, where your core sits, the box could be filled with gunk (branches, dirt, etc) if clogged will cause it to blow cold.
Just be glad you don't have a CJ...or God help you a YJ!! Everytime I used the "heater" in my YJ I felt like I was getting head from some 90 year old asthmatic that could only reach my ankle!

I'm glad you have admitted to getting head from a 90 year old asthmatic!!!!
Funny stuff!! I have an 89 YJ - the heater is probably the best running and most reliable thing on the whole rig.

Thanks for making me choke on my lunch. Too much info on your personal life. The heater in my CJ works fine, and I haven't even upgraded the fan yet.
Dude, you are too much. I laughed and had to read it to my wife. It was even funnier reading that out loud.
