Warm Rear Air Con

[marinabrid]

hi all

 

mk2 with rear air con,  the front is cold   the rear is warm,  no fault codes showings.    the two air con pipes under the car to the rear are the same temp   i know one should be freezing cold

 

Was suggested rear expansion valve,  have swopped this and regassed to correct amount for dual system,   still the same temp from the roof vents

 

Clamped off the rear water heater supply pipes    but no change in the roof temp vents

 

getting short of ideas now !!     

anything welcomed to get the back cold.  

know I'm lucky to have the front working !    ilke in my old mk1   but if its fitted i thought i will try to get it going.

I think there is a separate condenser unit for the rear unit. All the workings are behind the rear side panel.

yes  i have a parts picture that shows it,   could this be the cause of the fault ?

i have checked the flap door motors and both are working as they should    when on cold setting the inner flap is open exposing the evaporator and when i turn the heat up   that flap closes off the evap.    the other works as it should directing the    what should be cold air up into the roof vent or when heat up   directs it to the floor vent.

 

getting a bit lost for any other reasons

problem solved   someone in the past has cut the supply pipes in the engine bay.  so was never gonna get gas to the rear in this lifetime !
