V40 heater not blowing hot air

LS3 · Feb 14th, 2011, 17:01

Hi everyone!

New to the forum so hello to everyone.

On my third V40, this one being a '99 2.0T. One or two probelms, the first being that the heater fan works, but the heater isn't blowing out any hot air. When I start the car, the air con green light flashes and the recirc light flashes too, with a rapid clicking of what sounds like a relay from somewhere behind the dash.

Not too fussed about the air con working, but could do with some warm air - HELP!

Hi there

Does your engine warm up properly according to your temperature gauge? if not most likely to be a thermostat which is stuck open.

I've just replaced mine, £7 odds from eurocarparts and reasonably easy to do

warm cabin and better mpg now!

Yeah seems to - guage reads just below horizontal.

Wouldn't the air be slightly warm if the stat' was stuck open? It's baltic in there!!

Yeah, would be a little bit warm at least!! - not much though if mines was anything to go by!

sounds a bit more complicated - should be someone who can point you in the right direction

cheers shep

Just wondering if there's any links to diagrams of heating system anywhere?

Anyone know what the rapid clicking is when I turn the ignition on? It goes off after about a minute and seems to be coming from the fan area, though not from the relays I can get at as I've unplugged these and teh clicking continues....

Now have hot air - installed the patented 'manual override actuation linkage'.

...a length of plastic trunking lid with a hole in one end, pushed onto the white plastic stud on the hot / cold actuator gate behind the ashtray.

A pull or a push of said lever and I have hot or cold air on tap!!

Also sorted out that pesky clicking behind the dash' by emptying the gubbings out of the A/C actuator module - just unplugging it didn't work, as the fan wouldn't operate.
