Turned on heater and got cold air. set it to 90 and the the temp guage got to half and only got a small amount of heat. vehicle started to have windows fog had to turn on A/C to clear them. It was working fine just two days ago last time used.
I'm only getting minimal heat. It's full of antifreeze, thermostat works fine & system holds pressure. It was ½ gal. low on antifreeze when serviced before winter. All the hoses are hot & the guage moves showing center between H & C after warming up.
My heat wrks only a luke warm to cold temp then after warm up turns cold ..i flushed system an core..no problems..but still no heat knob not broken..and still no heat ..ac wrks great..
Everything works fine except when I switch it to heat, it blows cold air
Air blows cold, but when switched to heat, nothing but cold air comes out?
It's starting to get cold and I turn heater on and cold air comes out.
Truck warms up you can feel heat when you put the fan on it gets cold
i had the same issue in my truck which is a super cab xlt WITHOUT dual climate controls. all of a sudden one chilly morning on the way to church, no heat at all.
mine turned out to be the blend door actuator. dealer item in stock, cost me around $14, the part was cheap because they sell a ton of them. i changed it my self and it took me around 3 hours because i'm a carpenter not a mechanic
No heat for several weeks and now egine starting to overheat
no heat coming from heater. blower works and temps in line with normal
there is no water going through heater hoses therefore heater is not working
When turn on heat it blows cold air out
I turn the heater on and get minimal amount of heat blower is working
very little heat from heater, fan is blowing cool air
I replaced tstsat I get minimal heat. Could it be the heater core is plugged and can it be flushed out
