95 Fleetwood Cadillac no heat changed water pump and thermostat. The heater core is not bypassed and car stays defrosted help me see why no heat is blowing out. The fan works but no heat


Sounds like a air lock in interior heater core, remove one heater hose under hood and make sure you have flow through heater core. Some vehicles have a valve that controls coolant flow through heater, check on hose for that if no coolant comming out of inter heater hoses.

1996 Montero Heater Blower not working


I assume your heater setting is electric control, if so either your defrost and floor heat switch failed or wire problem. For the air not hot, check the heat control valve on the top of the hose it should be in front of the firewall. I don't know your car is using mechanic valve or electric control valve. Anyway check there first. Good luck.

Heater is just warm, when you turn on the defroster on high takes a long time to defrost. I have had the car since 2007 and this is not normal. p.s. already changed the thermastat


You could possibly have a bad heater control valve if the car has one. Another item maybe a stuck or faulty blend air door. This would be the actuator most likely. It may not be shutting off all the way to allow complete heat through. The other possibility is a partially clogged heater core.

No heat changed thermostat and just pulled the heater core which seems fine water from kitchen faucet flows thru both ways but cant find any control valve in the heater hoses to see if it is working


firs check both heater hoses are hot to the heater core after it is warmed up. If they are hot the heat cool door is not moving make sure the linkage for the actuator door is hooked up. If that isnt working test the module that moves it.If it is manually or vaccum operated there will be a heater valve inline the heater core hose. Make sure your vaccumm is supplied to the heater box from the engine. If it is staying on defrost you may be missing vaccum supply to the heater control. If it is electronically controlled the door actuator module is bad or not getting power. Sometimes the heater hand controls are the problem. sometimes the dash control separates and gives a vaccum leak.

No heat/defrost 01 corolla


Sounds like you have air trapped in the heater core when you flushed the heater core. loosen the upper most heater core hose and run the engine untill coolant seeps out. Wait until the coolant has reached running temperature.

Blowing cold air out when defroster on a little warmer when heat is on at my feet but not much


1st. make sure it is full of antifreeze/water. The defrost will be colder because the A/C comes on when defrost is turned on. The next thing is you may have a heater valve not opening as it should. Vacum or elect. heater valves have to open so hot water can flow for heat thru the heater core........hope this helps..

When the engine is cold,check the coolant level.

Make sure it's on max.

A coolant system should be flush every two years.

===

If you did a coolant flush recently then air pocket can be the cause of the un-even heating problem.

The DIY method is to drive you car onto a ramp or a steep hill.

Iet the engine cool off and top off the coolant tank.

Set MAX heat + MAX fan

Let the engine ran for 20 minutes wih the cap off and the trap air will escape from the coolant reserve tank,

Check coolant level and top off coolant when the engine cools down.



A shop will charge $75+ for this but using an air operated excavate tool!

========

A car with over 90K miles may experience linkage problem to the heater control valve.

The heater control valve (near the firewall) may be stick over time.

Open the hood and move the heater to max and min. Back and forth.

Clean and lube the linkage with WD-40 to free the heater control valve.

If it's a vacuum type heater control valve then cash for leaky vac. hoses.


=======
Move the fan switch back and forth to re-new the electrical conductors.

Pass a vacuum over the control panel to prevent dust build up behind the console.
