SOURCE: ford ka heater blows hot air all the time

Your problem is a faulty heater control valve. The design used on these vehicles allows for hot water to flow constantly and compete with the evaporator as there is no blender door. You have to replace the valve and possibly the control head. Meanwhile, you can bypass the valve to have cold air

SOURCE: my heater is set to 90 degrees and its blowing

you may have a clogged heater-core or low fluid levels in the radiator if one of the hoses going into the core is hot and the other is cold then it is most likely clogged undo both lines and facing the one down so not to get splatted with it use a hose and with minor pressure wash the gooey obstruction out until it runs clean and clear and flows free or you may also have a bad water pump open the radiator cap and with the car running look to see if its full and flowing and circulating if low add fluid if its not flowing i would say the water pump but give it enough time to exchange from the block to the radiator and if flowing replace cap or risk getting burnt ...also it could be the heat coils are not giving any help there should be a plug wire going into the unit near the fan /air-box remove the 2 screws and see it it turns red hot when switched on and also use a test light to ensure power is getting to it

90 CADILLAC HEATER BLOWS OUT COLD AIR


check the coolant level. If it is low the first thing to stop working is the heater.

If it is that low there is something leaking. A pressure check of the cooling system should help find the leak.

The heater in a 1996 cadillac fleetwood does not blow hot air when engine is idling, it is just warm, when the weather is very cold, (below 25 degrees.) when it is not this cold it seems to work...


I am guessing you have not changed your thermostat from a summer one to a winter one. If this is the case you need to put a 195 degree thermostat in to replace the 165 degree summer one. Let me know. Thanks.

My heater doesn't work. The blower comes on but no heat. Regardless of the setting (60-90 degrees) only cold air. Defrost works to clear windows but no heat.


Most likely your heater core has been clogged up with years of contaminants. The fix here is to pull the heater core, have it flushed or replaced, and put it back.

1999 cadillac deville 4.6 heater blowing cold air, set temp at 90 degrees


Besure that you have enough coolant. Your engine has head bolt issues and this allows compression gases into the sooling system, and this pushes coolant out and the heater goes cold before the engine everheats.... VERY expensive to fix correctly. There is a test to determine if exhaust gases are in the cooling system...
