Cleared all the faults down on my HEVAC and the only one still showing is Evaporator temperature sensor to ground - it is actually registering 65000 degrees. This is the only part I did NOT buy when I prepared to replace the blend motors :doh:

I cannot find the part at Rimmer Bros or Island 4x4 - anyone know where I can get one and how much? Might as well replace that too whilst the dash is out :croc:

May not be faulty,they do show 65 odd k degrees when they get down close to zero.Switch the AC off and run it a while,the temp should come back to a plausible level.Easy enough to change if it is faulty when the dash is back in.
Hope you didnt take the dash out just to do blends ?

Two of the three need to be replaced, therefore might as well do all three, plus o rings plus matrix temp sensor and get all done in one go

I'm not doing it any way - I am going on vacation instead

Same statement - none of those need dash removal,its better to do it all in place - two reasons,first its quicker,second you are less likely to break anything or have annoying rattles after.

Got back from vacation on Saturday - picked the car up Sunday - everything working

Drove up to Burton yesterday, footwell full of water

Popped back into the garage last night, up on the ramps, stiff tube poked up the LH drain and then about 3 ltrs of water dropped out - job done!

Parts - £230
Lab - £650

Ohh and they also sorted the oil leak out (duff pressure sensor leaking)

Hopefully that is it for the forseeable future.
