Air Con Rebuild


When I got the car there was no Air Con in the car and the fan for the heater did not work either. The fan was a simple fix, the resistor need replacing. The cool air site of the air con was a little worse. on the entire system, all I had was the compressor the two main pipes to the front of the car and an evaporator with both the connections snapped off..... So first things first make a list of what's missing, get it , fit it and gas it..... EASY :-)

Missing/Needed Parts:-  Evaporator core, Condenser, Condenser pipe, Accumulater/dryer, high pressure switch, low pressure switch, pressure release valve and an orifice tube. And then a leak test, vacuum out and a Gas fill.



The first job was to replace the evaporator core with a NOS. part I got from Dave Howarth. This meant getting inside the heater box in the depths of the dash. In this shot I have removed the passenger side knee pad and air pipe. I also removed the heater blower (right side of shot)

Here is the heater box again from further under, you can clearly se the hole where the blower was located. The trick now is to remove the bottom half of the heater box to gain access to the evaporator core, which should then drop out ;-)

Which it did, As soon as the bottom was taken out the core almost fell out, slight wiggle and it was free, leaving behind a large void. Top right of this shot you can see the air in let for the air con system. There is a vacuum actuated door  which is closed when heating the car, takes the air from out side, and then opens when you switch to cool to take the air from the cabin to be chilled.

Here is the offending evaporator core. pretty good condition, bar the connectors being broken off the end of the pipe work. the pipe ar now 2" too short. Replacement has been sourced and now fitted.

Condenser. This was also missing. Now in place it sits nicely on the front of the radiator. Again sourced from Dave Howarth.

This is the accumulator end of the condenser pipe, attached is the high pressure switch and opposite side of the pipe the pressure release valve. This end attaches to the evaporator where the orifice tube is.

And this is where it all comes together under the passenger side wheel arch, at the accumulator /dryer. Just Gas to go now, and hopefully I'll have cold air blowing... Just in time for winter ;-)
