How to fix my saab heated driver seat that gets too hot

As the heater elements get older the parts of them can break down, when this happens the overall resistance reduces so more current passes through the existing elements, causing those left to get hotter.
If left they will burn out completely, there is also a possibility they could damage the upholstery or even catch fire.

Rattling sound when I slow down. Sounds like a bad water pump but the sound stops when I disengage the clutch and stop even though the engine is still running.

The car is over heating. Check the coolant level. Have a pressure test done to check for ;leaks. Have a compression test done to check for head gasket and cracked head/s. Normal operating temperature is between 85 and 95 degrees c and if as you say is 20% hotter then it is boiling

Audi a4 2.8l no heat

take the top off the filler cap run engine to boil. keep it full off water to the top. you will see air bubbles coming out as the engine gets hotter. squeeze the pipes on the rads to help the air come out. when fan kicks in turn engine off and leave to cool down.while you are doing this make sure the fan for heater is off but is on full heat. can have fan on number one on speed that is fine.

2004 chevy aveo when i turn ac on it runs hot and when i turn ac off it cools down

The AC puts allot of heat load on the engine so of course it will run hotter but not overheat the engine, if that happens you may have a clogged radiator.

Why does my 2001 Chevy Monte Carlo get hotter when traveling at high speeds with the ac on?

the A/C works the engine harder than normal at any speed but adding high speed with it increases how hard the engine is working therefore its going to get hotter. As long as it's not over heating your fine. look at it this way if you walk you may bet hot but if you run the same distance chances are you become hotter faster.

Car only overheats when a/c is turned on.? is there a coolant temp sensor or not?

Yes there is a sensor. It tells the PCM the engines temp and from there a number of things are going on.

Have the car running and turn the a/c on and look under the hood at the cooling fan(s). If the fan is not on immediatly wait for a minute as they may come on when the a/c pressure rises and not right when the a/c is turned on.

The a/c condensor gets very hot. That would make the air being drawn in hotter than normal. The engine temp may rise higher than normal as well. Is it really over heatting or just running a bit hotter.

The heater gets to hot. turning the heat down offers some relief. the area around the vents get too hot to even touch. is there any way of adjusting the system ? Is something malfunctioning? Thankyou,...

i would assume that it is working properly. the heat can get no hotter than the coolant flowing through the heater core. i reccomend turning the temp control toward cool a little bit
