Heater
Ok I have read the forums as I hate to ask repetitive questions and I have found many people have upgraded the heater and defroster in there Jeep BUT they have the 4.0 engine.
I have a 2.5 stock and the heater puts out very little heat and hardly blows. Has anyone upgraded there stock 2.5 and can give me a few options? Much appreciated. ST

Flush or replace the heater core, check or replace the thermostat, make sure the actuator cables are hooked up. One of those will make you sweat!

i have a 2.5l and the blazer heater motor works great. I just upgraded it about a week ago. what a difference. just go get part number pm102 at AutoZone and switch it out. if you search "heater upgrades" you will find step by step on how to do it.

I have to turn the blower down to the half setting after the water temp hits 180 because it gets too hot
 As far as I know, mine's stock. Cowl vent clogged? I pulled a ton of leaves out of mine before winter. Also, thought this was somewhat relevant here, might build them: http://www.jeepforum.com/forum/f12/better-heat-yj-122052/
