Hi All
I'm trying to repair my heater controls. Forty years of other peoples bodges and neglect have not been kind. The switch block is quite complex and is a mix of electrical and vacuum switches
Is there a diagram of which hose (blue yellow black etc) from the heater control goes to each box flap control ? I've tried trawling through the web and all the manuals I have but there is nothing to see. It must be in a manual somewhere.
I have the dash out as it is cracked (I have a refurbished one) and I could see that much of the vacuum stuff was not connected. I can't tell either if the water valve (on right side lower of heart box) should be vacuum or cable. I think this should be vacuum but has been replaced with a 'cable' one ánd tied open. There is no control to match a cable operation so it must be from the 'MAX' A/C setting that should shut off the hot water (maybe)
I have some certainty that the black pipe connects to the top right of the heater box which must be the inlet flap under the wipers
There were a lot of broken parts on the heater box and the cable control for the temperature slider.
I've fixed these but need to work out where the vac lines connect. I have a vac pump so I can test it while its in bits
I think the electrical connections will be OK but it would be nice to know for sure.
Thanks
