Heat not working; my blower comes on but its not hot air, any ideas?


The temperature blend door is stuck on the A/C side ! Do you hear a clicking noise behind the dash ? Has an electrical controlled actuator that switches a door inside heater - A/C box from A/C to Heat . So the blower is blowing air over the A/C evaporator core all the time , not switching !

Air Conditioning of my Renault Megane is not


Hi

Have the driver's door window open and the front bonnet open,
we are going to listen for a clicking noise, the noise that we are listening for is the Compressor engagement being activated after three seconds from the control panel.

Start the engine and switch on the air conditioning by pressing the AC button (with a request for maximum cold temperature and the passenger compartment fan running).

If you hear that clicking noise, then it is most likely that you have a leak from the AC system or a possibly in need of a top up do to service of the system not been carried out.

Otherwise if you don't hear that clicking noise then there is a case that the Compressor clutch is not being engaged.

Do to the following reasons

1. fuse blown in the UPC in other terms the fuse box (engine compartment)

2. AC Compressor faulty

3. AC pressure switch faulty

4. If there is not the slightest bit of pressure left in the system which is very unlikely.

I hope this information was somewhat helpful for a real diagnosis test a diagnostic tool is needed.

Enjoy.

Heater&air conditioning vents wont reach position make a clicking noise have no heat or air how do i fix? 2003 ford explorer


The clicking noise you hear is a stripped out plastic gear from the blend air door motor almost every car maker now uses little electric motors to control heater door panels,put it in the position for it to make noise go under your dash find where it is usually externally mounted remove it and replace it cost about 30 dollars at the dealer.depending on which of the 3 motors its is usually not hard to do.

When engine is started, heater door makes clicking noise for 20 seconds and quits. When engine is shut off, heater door makes clicking noise for 20 seconds and quits. Door makes clicking noise when heat is...


Your air temp control blend door actuator is failing, that is the part u call a heater door, it is a gear driven miniature drive, the gears are jumping teeth making the noise, it will stop working very soon.

2000 ford windstar heater blowing cool air


Hi, You may have an air lock in the system. Have you ever had the system flushed out? This might be the fix. Also the thermostat might need to be replaced. You didn't say if you hear the clicking noise. If you do hear the clicking noise when you adjust the tempture control then its back to the replacement of the blender motor box with broken gears.
Hope this helps Warren
