heating problems

[bczelenski]

Hey all, i just installed a new thermostat, due to heating problems, but it still wont heat up properly it heats upto appr. 75degrees or a 1'4 of the way on the temp gauge then just stops and wont go any higher and the heater will only blow semi warm air. is there anything else that comes to mind that could be causing my problems . thanks a ton

I have the same problem on my 98 D. I changed out/flushed out my coolant system which improved a bit but still about the same warm air. Id like an answer to this too.

Both you guys probably have stuck-open thermostats. The motor never completely warms up and so you don't get hot air...

Could this be the heater core too?? ....or a plugged up hose or heater door inop??

I don't think so because the engine temperature doesn't even get high enough like you said. If the temperature was at center on the gauge and it was still blowing semi-warm air, I'd figure it was the heater core or something else.

I have a 98 durango, and like all of you I have the same darn heating problem. I have replaced the thermostat twice. It is in such a pain in the ass place too. the first one the thread got stripped so I had re tap the hole with a jimmy rigged handle 12" long. So I don't think its the thermostat getting stuck open unless I have bought 2 bad thermostats.

Alright I just bought a 98 Durango with 70K on it and the first thing i noticed was that the heat is not hot, LUKE WARM AT BEST. i had the thermostat replaced and still not luck.....The engine temp does not come all the way up to the middle of the gauge like it did in my jeep. HELP PLEASE

It's the Heater Core. Same thing here and that fixed it after replacing therm, climate module, etc...
