Could be quite a few things. I am under the assumption you already checked the fluid level. If that is the case, I would ensure there are no air bubbles in the system and or no leaks. A leak or a bubble will not allow the system to pressurize and move fluids through the radiator where the fluid can then be cooled. Also, I do know that some VW's suffer from the water pump fins cracking off which doesnt allow the fluids to circulate like they are supposed to. The last and final thing it could be is a clogged heater core. You can try by passing the heater core and see if that fixes the problem.

I would check in the following order and test after each one
1)Check Fluid Level
2)Burp System
3)Replace Thermostate
4)Bypass heater core and see if problem persists
5) All else fails replace the water pump.

Good luck

2006 cvo FLHR touring white smoke coming from heat shield right before the exhaust pipes. What could it be cleaning material used on chrome, or mechanical warning???

Is the smoke constant while the engine is running? Take the heat shields off and check for cracks, leaks, or loose exhaust bolts.

2005 Ford Expedition: Constant thumping sound from dash when air/heat is on or off

Usually this is caused by a binding blend or mode door. The actuator keeps trying to move it and can't. Locate the exact source of the noise. Then disconnect the actuator and try opening and closing the door by hand.

2005 Saturn relay has intermittent heat. You have to adjust all dials many times until heat kicks in. Once heat works, its plenty warm. The frustrating part is it is so random. Have read about blend...

Sounds like it is low on coolant. Add coolant, drive the car, let it cool down, and then repeat the problem until the coolant level stays constant in the coolant tank. If it doesn't stay constant after a few tries, there may be a coolant leak inside the engine (blown head gasket or intake gaskets).

Whining Noise Near Rear Differential

indicates a fuel pump problem as that is the only thing in that area that is ignition controlled or possibly the EVAP system solenoid/ valve if it is in that area
the frequency will be constant as the pump rpm is constant
the noise could be a venting noise from the EVAP in in that area
the distance of 15 km indicates that the problem is heat related as it take that long for something to over heat and cause the noise
you may get an indicator by running the fault code

When i turn off the ac, there is a clicking sound coming from the dash on the passenger side, what could that be?

It could be that the metal ductwork is now heating up and expanding after being cooled. But that isn't a constant click, very intermittant, so if your clicking is constant that wouldn't be the problem.

If it is a constant click it could be that you passenger side sensor is calling for increased cooling and not senseing that the AC was turned off. If the clicking stops after you turn the engine off and then immediately restart it, that is probably the sound.

My 2005 ford escape seems to have a heat issue. When the heat is turned on at it's hottest, it's hot, however when tuned down to the midway point, it cools down quite a bit, what may be the issue ?

I assume the vent door is loose or broken,and when it is set,maybe half way on the dial,the door moves to far closed.It is either that,or the control is bad.
