1996 chrysler cirrus heater fans not blowing hot air to vents or defrost. Not sure of actuator or thermostat. Since i dont know where they are. 2.5L V6 - 4 cylinder.


I will assume that your engine is full of coolent, and does not overheat. Now if your car takes like forever to heat up, It will be that your thermostat is stuck open, but after a while, you would have heat in your car. If your engine coolent hoses get hot, but your heater hoses do not, remove the heater hoses where they connect to the engine. This is the first place dirt, grime, and corrossion build up, stopping the flow of hot coolent from going through your heater core. (heater hoses stopped up at engine/waterpump connection.) Your heater core may also be stopped up if there is alot of corrossion present.

The thermostat is located directly under where your upper radiator hose connects to the engine.

Have a 93 toyota have replaced the heater core and the blower fan and also had to replace the relay, after replacing the blower I can hear and feel the fan blowing but I barely have air coming out of the...


no. they probably cut the duct work so they could change it easier. open glovebox and if you feel lots of air in there they didnt do the heater core correctly. u may even see the plastic all broken behind glove box. they got lazy.

88 bronco II, heater hose going to water is cold, and my heater blows cold air, is my water pump going bad? the return heater hose is warm, it was heating once in awhile now it don't heat at all just cold...


I would try flushing heater core to see if it's plugged. I don't think it's waterpump, your rig would be overheating if it was. Leaking is most common waterpump failure.

Changed thermostat and added coolant but 1997


could be waterpump?
i was going to say rad fan,but if so heater would be hot.
lack of coolant will make heater core to blow cold,if engine heats up with full coolant,usually means poor or no circulation.
water pump?
run engine with full coolant,at operating temp.with rad cap off and look in rad cap hole and see if there is movement of water inside rad.
[rad fan will not come on if water is not circulating through rad water pump?]

No heat from vents with climate control. heater core is hot. fan is okay, changed out air blend motor, ac works great, infact it seeems to be on all the time?


Did you change the one behind the glove box door? If so you may have something inside the heater box keeping the door from moving completely open or closed.

Where is the water pump located on a 92 integra? also where is the heater core located?


the water pump usually runs behind the large fan in the front of the engine. two large rubber tubes run from the water pump to the heater core, which runs through the passenger-side firewall located right behind the glovebox.

Water not circulating,we put on radeator cap water pump ,intake gasket,flush heater core,engine radeator,reservoir


check to make sure the bottom radiator hose is not collapsing. sticking together. once it sucks together its like the thermostat being closed. the faster the engine turns the it sucks together. also make sure its not the clutch on the fan gone bad. if it has one. to ckeck ,look under hood at fan ,have someone to rev engine. make sure the fan turns as fast as the engine turns . if it doesn't it's a bad fan clutch. goe put a new one on.

1999 Audi A4, european car. When air conditioning has been on for a while and you turn off the engine, water comes into the footwell on the passenger side of the car. There is never water under the car...


Yes there is. The drain should come down from the heater core area (behind the glovebox) and down under the car. Yours is either clogged, or for some reason has been pulled off the core, so that water just flows from the heater core drain nipple directly into the car.
