Probably not but it can switch from heat to ac if this answers your question
First responder is correct, if you have a system know as a heat pump. If you have separate heat and A/C , having you A/C turned to extreme cool may cause your heat to come on. A window unit blowing hot and cold simultaneously is indicative of the A/C motor overheating, and could be dangerous.
Not a good idea.
Likely heater core. I had same problem with 1996 S-10 with 4.3L.
I have the same problem. Change your heater hoses, top and bottom !
Heater core is on the passenger side behind the glove box, this is also the location of the air conditioner evaporator core.. they should be in the same housing.
I have exactly the same problem on my 2000 Still looking for the answer
No it's not ! It uses electricity to blow cooler air into a home - the same effect can be achieved by opening a window !
hi, did you faind an answer, i'm having the same problem, Cheers
That can happen if they are low on freon.
Air in the water system.
I had the same problem...until I had the coolant in the AC system recharged two years ago
Having a room heater and air conditioner in the same unit provides convenience and cost savings. It allows for year-round temperature control, making it easier to adjust to changing weather conditions. Additionally, a combined unit can be more energy-efficient compared to using separate devices, leading to lower utility bills.
that heppend to my car i had to finaly replace the heater blower so it could be the same thing
