Heater Problems

my heater only blows hot air   .  even when i shut the fan off, the vents still let out hot air (although not with any force).  the slider control for the temp in the dash seems to be very slack - could it be as simple as the connection to the slider has come off/broken?

any one got any pointers?

cheers

Move the heater valve by hand inside engine bay and go from there mine done the opposite! sticky thats all mine was.

cheers - i'll try that for starters

I have the same problem and when its nice and sunny outside :dontknow:

The controls behind the slider might be at fault.  My sliders just flop around because the control assembly is no longer fastened to the dash.  The assembly mounts to the two screw holes in the bottom with plastic tabs.  But if the tabs are broken, then the slider will not actuate correctly.


As a result, I usually have full time heater vents even during the summer. :roll:

I have the same problem of constant warm air.
 

To repeat Dougloves advice; Open the bonnet and move the heater valve cable by hand to close it. No more warm air. Put it back again at the end of October....

If you still have your heater prob look at my solution on big block engines.

just got back to this post chaps.  where abouts is this heater cable that needs manually moving?  not a mechanic by any stretch! ops:

Hi JPX is yours a left hand drive,I see in your pic you have removed instrument cluster how do you pull apart heater blower switch?

OK guys it seems a lot of you have the same problem I had.
1st get a friend to check whether the little black plastic flap in the engine bay on the end of the cable is moving full stroke between the 2 stops on the valve, whilst you are sitting in the car moving the slider control from hot to cold. It must travel to the plastic stops on the valve, or it will not close fully.
If it is not, then manually move it to its full closed position, if you can, then see if your heater blows cold. If it is still blowing warm then you need to replace the valve attached to the end of the cable. As previously mentioned about ?12 from EuroCar Parts.
If it is now blowing cold your valve is fine. then you have to reset the cable so that it operates full stroke to the 2 stops on the valve when switching from hot to cold.
If the cable in the engine bay is not moving when you move the temperature slider from hot to cold then the cable has snapped or become disconnected somewhere.

Hope this helps guys! have pictures but not worked out how to attach yet, any pointers welcomed!!!

sorted!!   i now have cold air blowing!!!  

the valve was being obstructed from moving full stroke by a jubilee clip.  easy fix anyway and the girlfriends is into single figures with complaints about my baby - bonus! :wink:

now just need to sort the carbs, radiator, passenger window, temp gauge, carpet, door hinges, stereo, mfa, steering wheel boss…………..and the list goes on   :?

Keep up the good work, I drive all sorts of nice cars but nothing gets more looks and admiration than my clipper!!!

I would be very interested in seeing your pics as I still have constant warm air - so much that I always drive with my roof down even when the sun is not out!

I fitted a new heater valve at the weekend - can finally drive around with my windows shut & just in time for our indian summer ….
