SOURCE: volkswagen jetta over heating

hi tammy
it could be an air lock stopping the water from circulating properly i seem to recall this problem on the older VW Derby and audi 50 (same engine) there is a small bleed screw at the highest point on the cooling system that allows you to bleed this air out youll find its location in the manual

another thing to try is put a flushing agent through the system incase there are any blockages in the radiator itself

hope this helps

Is the blower motor working? If not that is what it is. If it is working then check heater coil out, Could be bad heater coil.

SOURCE: 1996 jeep grand cherokee blower works but no heat

Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

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.

My suzuki alto stantard SZ 5 DOOR 2012 modle heating is now working Please advise


HVAC, the heater is not working?
the resistor only makes fan work , on low speeds.
1: is the fan blowing? heard and felt? on HIGH?
2: is engine coolant at 180F temp, or more holding, IT must, or there will not be heat,.
3: are both fire wall heater core hoses hot, fully? if one is cold the core is blocked. (flush it out)
4: Ok, we have hot water coolant to core (heater core) so is the damper open?, yes, then now you have heat for sure.

if all that is greek , get car serviced.
or buy the FSM book read , HVAC chapter
the factory service manual

99 ford contour gauge shows running hot. Change both sensors near thermostat and the thermostat. Flushed system and burped it. Ac or heat makes no difference. Fans seems to be working. Any ideas?


Is it ACTUALLY overheating? Check for heat at the top and bottom radiator hoses, and at both heater core hoses. If one is cold then your radiator or your heater core may be plugged and in need of a individual flush.

No heat is there a fuse 2003 f250 is there a fuse for heater


i don't know realy if there is a fuse (though i doubt it) but issues with heatting may be this will help.

If the carpet under the heater core is damp, or if antifreeze vapor or steam is coming through the vents, the heater core is leaking.
Remove it and install a new unit (most radiator shops will not repair a leaking heater core.
If the air coming out of the heater vents isn't hot, the problem could stem from any of the following causes:
  • The thermostat is stuck open, previnting the engine coolant from warming enough to carry heat to the heater core. Replace the thermostat.
  • There is a blockage in the system, Preventing the flow of coolant through heater core. Feel both heater hoses the firewall. They should be hot.if one of them is cold, there is an obstruction in one of the hoses or in the heater core,or the heater control valve is shut. Detach the hoses and back flush the heater core with a water hose. If the heater core is clear but circulation is impeded, remove the two hoses and flush them out with a water hose.
  • If flushing fails to remove the blockage from the heater core, the coremust replaced.

Heating Problem w/2000 Plymouth Breeze.


Sounds exactly like what my mom's car was doing as for the blower only working on high. It was the resistor... I assumed it was the climate controls and replaced them but it didn't change anything then i thought that i must be the blower motor and replaced that too but it turned out to be the resistor which is under the dash on the passenger side of the car.
