The airflow is great through every vent so im not sure what to check. Did you guys say there is no air control valve on my year or there is? If so i will check out that. How do you do a reverse flush of the heater core? Can you do it while its still on the car? Thanks for all the help.

thanks a lot, im not going to rule out the heater core but the carpet is dry and usually the carpet gets soaked whent that goes out if i am correct. How would i check for the plugs in the hoses? Also, the heat is warm then drastically cold at the slighest movement of the control knob. Thanks!

Yes, it did exist before but, and thats what i thought the problem was so i changed it, but i still have the problem. Thanks for the help!

I have read some other posts on this and i just want to know if anybody has any ideas. I changed the thermostat and just did a COMPLETE tune up on my car along with cv-shafts, and clutch and exhaust. My heater heats to slightly warm but not hot. Does anybody have any ideas. I didnt refill the car on ramps after i changed the thermostat then i read a post about that. Could that have anything to do with it, and if so, how do i fix it. Please help out! Thanks a lot!!! The car is a 92 loyale 4wd. Guedo
