Why is My Car AC Blowing Hot Air? - BlueDevil Products

Is your 3800 producing normal heat? If so, the temp sensor is probably bad...If not, try replacing the radiator cap...if your system has air trapped inside, it usually runs hot, not cold...the heat is the key to functioning properly for you...Your radiator is a 4 stage huge system that normally cools very well...if you have heat, I still think your temp sensor is bad...ask to see one at your parts store, will help you to locate it. Hope this helps.

the heater core is failing or u dont have enough fluid--driving is takin the temp down--replace blower motor and ac evaporator when u change it since it a major job

Sounds like the heater core

Not sure I follow your wording on the different temps. If the system is full of coolant and working correctly, the thermostat should open at 195 degrees which would be several miles down the road. Once the thermostat opens both radiator hoses should be warm. If the water pump is not working the engine will get hot very quickly.
Have you tried running without the thermostat to see what happens ?

did you let excess air out of radiator? after filling let it run for a few minutes with out radiator cap and make sure the water does not go down and serculates after thermostat opens, refill if needed
do you notice moister under vehicle in the morning ? possibly a gasket could be leaking.

You have an air pocket in the cooling system. To bled it out you will have to park vehicle on an incline or jack up the front end untill the radiator cap is higher than the heater core. The remove radiator cap and run engine until warm then hold rpm to about 1200 rpm's and top off coolant level until you have no more bubbles.

if you see the water leaking form the front side of the engine usually from the water pump since the pump is not running you also wont get heat, bit when you pressurise the sys you are forcing the hot water into the core and you have heat, it is the water pump.

1 Inspect Cooling System Mix Coolant level low or flow is restricted. 2 Inspect Thermostat Thermostat stuck closed 3 Inspect Heater Control Valve Leaking or defective heater control valve. here something to help u
