Air Con Wont Blow Hot!

[jadams2]

Hi,having just had to jump start my galaxy 2.3i ghia 2000,now the air con/heater wont blow hot,sounds like the compressor is not clicking in and out as it should,i have checked the fuses and all seem ok.could i have blown something while jump starting? or is the compressor dead.

Ja.

In this weather I don't think you need the air con compressor! Set the the climate cotrol or temp control to 22 deg C and drive for asbout 15 minutes or 10 miles. Does it get warm then?

iirc my compressor will not kick in with these low tempratures we are all having.turn on aircon to see if the clutch plate is spinning?

[Mirez]

A/C Won't engage below around +4*c so that'll be why your compressors not kicking in. As above after a 10 mile journey you should have heat, if its *just* starting to come in then the most likely suspect would be the thermostat.

have driven car well over 10 miles,temp gauge goes to half way and stays there,no signs of overheating.climate controls direct air flow up and down and via the vents as it should,if i increase temp on display it just continues to blow cold air.

Ja.

Does the rear heater blow hot ?

 

 

 

If so it is a faulty flap motor on the front heater.

 

If not then it is an engine/thermostat problem and not an aircon/heating problem.

Engine warms up as it should,all climate controls work fine only blowing cold air regardless of the temp set on display.

no heat coming out of anywhere,all climate controls and fans work fine,drove the car about 15 miles and temp gauge goes to halfway and stays there.

Could be Thermostat or even an air lock

sounds like what happen to mine and it was the heater matrix

[Floydey]

My Mk2 Tdi has suddenly stopped blowing warm air despite the fact the temperature gauge is showing normal, when you say "heater matrix" what exactly do you mean?

[edatelder]

The matrix is the heat exchanger within the dashboard area where the heat from the water is transferred to the air blowing through it. It's like another radiator. Due to the small bore pipes within them they can get blocked.
