Heater Stuck On Hot Blows Hot On All Settings 02 1.9 Tdi

Hi

 

i have a galaxy 02 plate 1.9 tdi lx

 

since i got the car theres always been a problem with the heaters in the front, first the heater air blowing from the vents in the front seemed to be very poor, even if you swithed it from fan setting 1,2,3,4 it never seemed to come out of the main vents, but just a small amount of air from the side air vents that point towards to side windows

 

i just brought a new heater/air con switch of ebay

 

now to heater blows abit more, but its stuck on blowing hot air only, and always blowing air on the windsreen

 

the new aircon/heater switch has increaded the heater airflow, but as mentioned it stuck on hot , turning the heater switch to cold or hot makes no difference, it just pumps out hot all the time

 

and as mentioned its stuck on blowing only to the windscreen, switching the control switch to floor, main vents etc does nothing, it just pumps out to the windscreen vents only

 

does anyone have any ides about what this problem could be????

 

all the swicthes that control the vents and temperture seem to be electrical items, could there be faults on relays or sensors or other areas causing my problems

 

thanks

If you search the Forum for "Heater Control Panel" you may find the post that comes up helps. We have had the same problem twice and this worked for us. Basically the controls stick in one place where you last left them when the contacts fail. Have a read, it's a long post. We had a similar problem again but that involved further electrical failures and you haven't mentioned any of them!

 

Good luck

thanks for the tip on the other subject but i still have the same problem

 

i have removed the heater control panel, switched on the ignition as mention brefily then reconnected to try to get it to reset, but this is not working

 

i whould think the problem i have is with something other than the heater control panel itself, as i have 2 heater control panels, the orginal and one i got from ebay that was confirmed working, with both units i have the same problem.

 

the problem is:

 

1: air flow from vents is stuck on windscreen only

2: center heater switch works on settings 1-4

3: left heater hot - cold dial not working

4: right air flow screen, front, floor dial not working

5: aircon,and other 2 small switches not working either

 

i have tryed getting a manual for this car 02, 1.9 tdi lx galaxy, but theres none available it seems

 

there must be some relay or other fuse/switch thats at fault here, there was also mention of the flap that controls hot/cold air getting stuck or the servos that move it, but how can this also affest the other item, ie the air flow to screen or floor, plus the air con , recirlate switches etc

 

if anyone has any ideas, it whould be very usefull

You need to get a diagnostic scan, the fault(s) should show up quite clearly.
