I have a 2000 Dodge Stratus, a few weeks ago my car overheated, the day before it had quit heating, only blowing cold air. My son changed the thermastat, also took the hoses off to make sure no air bubbles. The car seems to be fine now but still not much heat, thermastat gets up to just under half way. I did start having heating issues last year and my son changed the thermastat then too, but it never did heat any better. I am wondering what else could be wrong?
Thank You for writing into AskPatty! To address your concern,(1) your blend doors located inside your HVAC duct in the dash may be skewed. You can find the IOD fuse on the driveside fuse box location typically the only fuse that is elevated, unplug it for 30 seconds, this can cause the AC head do a recal of the doors. This may also reset the radio on the same circuit. (2) You may have a failing heater core, after performing the recommendation on step (1) if this has not fixed your concern you may need your heater core function inspected.

I would be concerned with the flow of coolant through the heater core, and the condition of the fluid in the system. If both of these seem good, The next step is to find out why heat does not transfer from the heater core to the cabin. Possible causes could be a clogged heater control valve or blend door not routing air correctly.
Hope this helps! Thanks for your question!
