I know there are several posts on this but haven't found my answer in them. 96 ranger with 4.0. I replaced the thermostat and now it runs in normal range of temp gauge but still no heat. I assume the blend door is the one behind glove box? It opens only when selector is on "off" or "max a/c". The vaccum line on this door extends to the valve on the heater hoses so the valve only opens in the same two positions. If I manually close the valve on the heater hoses it still doesn't get hot. Are these the correct times for door and valve to open? Maybe I have 2 problems and need to flush heater core?
Also the a/c compressor comes on sometimes when the selector is not on a/c. Is that normal? I unplugged DC wire to compressor so it stays off and heat still doesn't get hot.
Hope someone can help...
Thanks
