heater system - no hot air blowing out.

on the 83 plate mk1, when the system is switched to 2/3 you can feel the air blowing out, but its cold! not very good for the cold morning. I drove the car for a hour, but still was cold.

Is it not blowing hot air out, because the matrix has gone?

cheers

check the valve first.  Right hand side engine bay, towards rear, has a cable connected - cable operates a lever that opens and closes the valve.  Probably the cable is disconnected.  You will only get hot air at your feet and windscreen - side vents designed to only provide fresh air.

Valve is located at position 16 in the following:

Down next to the left of the servo

ahh thats answered my question about the side vents only blowing cold air

cheers chaps!

They don't have to! I modified my heater box to blow warm air through the side vents, or cold air when heaters off….much nicer in these cold mornings, gives warm air on your hands (right hand only unless you do my other mod of adding a centre dash vent!) - posted pics of the mod ages ago, can't believe everyone hasn't done it!

wheyy im well up for the modification!

any possibility you can show me the link?

its a great idea and winter is just round the corner  :wink:

check your car has enough water in it mate, if your matrix has no water it, it want work, or you may have a blockage, in that case open the valve to hot while the car is running with the blowr on, this mite help
oh and top the water up

Can't work out how to do a link thingy, so will try to bump my old post on this for you to try.
Should be headed 'Top tips for warm hands this Winter" - I've tidied the dash fitting a bit since
