Air con issues

[bertman]

Does anything inside the ecu contol the aircon
Had my ecu in and out several times to send off for upgrade and a repair(apparent fault in ecu).The car was off the road for a week or so.before that air con worked fine,now no cool air or tell tale blip when switching on.
Also engine has cut out a couple of times when turning fan off when air con switch is on,fournately when only stationary.
Noticed a splattering of water droplets in passenger footwell.
Always worked fine before ecu removal.
What could I have disturbed that may cause thisI have checked connections are tight.
Cheers

AC and ecu 'talk' re rpm adjustment via ISV to compensate for additional engine load and WOT shut off of compressor. The MFTS may do (see thread)
From my recent experience with intermittent AC (check the threads) it sounds like a poor connection. If you have had the ecu out a few times you should not have disturbed any AC related wiring under driver side.
My guess is the ecu connector is either misaligned or a pin has broke. I would unplug and check.

Of course it could be coincidence !!
