you have a bad control unit, the thing you use to switch from one thing to the other, it needs to be replaced.

SOURCE: Very low air flow through vents despite the fan working well

It is very likely that the Air conditioner evaporator core is restricted due to leaves or some other object may be blocking air flow like a plastic bag, does it do this on both outside air and recirculation setting?

SOURCE: ac system

take the dash off to see if the vents are connected to the dash. if not, the heat from the engine is blowing through the open hole

What could be causing loud grinding noise when i switch on aircon? Aircon now not working but only makes loud sound.


Sounds like the bearing or part of the clutch in the A/C compressor has failed, or possibly component on a/c fouling on something due to recent repairs however would be unlikely and probably just a coincidence..

Check A/C compressor turns by hand, should be firm but not make any noises.

Check for fouling components related to a/c compressor clutch.

I drive c240 2005, when i turn the front glass fog air blow on, it give loud noise and now air comes out, it seems that pips are blocked somewhere.. NOT SURE WHAT TO DO


Do you mean that the air does not come out of the vents at the bottom of the windshield?

This could be as simple as a vacuum leak or a broken leaver somewhere in your dashboard. I'm a big fan of fixing it yourself but I think this one is going to be easier for a dealer to fix.

91 ciera only does defrost, no vents or AC


i believe this is a vacuum operated system. if there is a problem with the vacuum supply to the control unit, it will automatically default to defrost. i would start by checking the vacuum source lines. good luck!

Could be the flap that directs the air flow. Are you getting air flow to all vents? The flap is inside the venting and controlled by a vacuum operated actuator.

AC dead? Acting strange like a Stephen King novel


do not interfere with this AC system ,you may be able to change the fan motor but be careful with the AC pipes ,if the pipe cracks and gas escapes it can cause frostbite in about 1 sec flat .Now the most likely cause of the air flow in the front not working correctly is because either its got a split rubber pipe that connects to the operating valves or the diaphram in one of the valves has split which means a replacement operating valve ,if you listen carefully you mey be lucky and hear a hiss somewhere

Air conditioning fan makes loud noise the faster you ru it.


Concerning your broken vent -- this can be caused by a broken linkage or a malfunctioning servo motor as well. these vent have air ducts the sway back and forth to adjust the dual air flow function. if the servo o linkages are malfunctioning or not connected for some reason, it will not allow total control of the air flow and temperature range. Now, if you have a combination of a flow error and temperature error as well, thai can be caused by a combination of the two.

In this case, you will need to inspect the linkages as well as the servo motor function as well. in addition, i would test the air temp sensors for there operational value. they control the temp when you adjust the coll or hot function.

Concerning the Loud noise coming from the blower fan---

This issue can be caused by a misalignment within the blower housing or, it can also be caused by some minor damage within the motor itself, causing it to rotate in a erratic manner, in return, forcing it to rub against the housing itself. the best solution here is to extract this blower fan housing and inspect for lose fan propeller and motor stability. replace parts accordingly.

PLease rate and have a great day:)
