under the dash pass. side look at heater you will see a plug with several wires that look like thy go into the heater there is a one screw plastic cover over this area so your feet dont hit it remove then uplug the wires then take the 2 screws out of oval shaped sensor and pull it out of heater you will see some transister on the back side and a little coil . replacing this will cure it usually . but first remove your heater blower and make sure it turns freely and not seizing.
it could be the heater is leaking!
A bad smell coming from the heater in a vehicle can indicate a bad heater core. One way to check this out is to see if the smell is worse when you sit in the passenger seat. If it is, there is a good chance the heater core is bad.
the air conditioner and heater are two separate things.(not connected) ;) it may have a fuse. or the it could just be bad.
If the air conditioner in a Mitsubishi Legnum is not working, there could be a blown fuse. There could also be a loose cable, or a problem with the heater motor.
The compressor could be bad.
heater core could be rusty and old or line to heater core could be plogged most likely old heater core
A blocked heater hose could cause a leak. A stopped up heater core could as well. Or the connector in the Windstar could be cracked.
drain for the air conditioner heater case could be stopped up,or a heater core leaking... !!!!
If it is broken. It could be a faulty temperature blend door actuator.
have you checked the engine thermostat. I have a similar problem..no heat or air. according to a service manual there is a door at the heater core that is supposed to open when the heater switch is turned on. this could be the cause for both of our problems. any ideas for getting to the heater core?
Could be a bad heater core...also, could be low coolant level. With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
Blocked heater core, faulty heater valve, disconnected connection to the heater valve.
This has much to do with how the air conditioner and the heater is vented. If the air conditioner draws its air from outside it could be picking up air / smell of smoke from the other family and then redistributing it into your home. A heater on the other had usually has a heater input vent within the house it is heating (it draws the interior air in and then heats it blowing it back out) as the air within the home will be significantly warmer than the exterior air.
My 89 jeep Cherokee surges at idle and sometimes stalls but runs fine once you are going what could cause this?
It could be steam from the heater core
It may be out of the coolant or a bad wire. The fuse could be the issue as well.
a bad water pump could cause low heat. The heater uses the coolant from the pump to generate heat.
Yes it could.
if its ac it could be freon if its heat could be carbon monoxide.
Loose wire on blower motor? Broken bower motor resistor? Bad blower motor? Loose fuse in fuse holder? Bad fan switch?
A possible cause could be that you have a clogged heater core.
