Hi all,

Got a bit of a strange problem this morning. I accidently flattened the battery last night and disconnected the neg terminal at one stage while setting the charger up.

All is fine this morning and codes relating the the flat battery cleared through forscan, however the air conditioning no longer gets cold. The button indicates its on, the vents all work correctly, the heater works fine but no cold.

I checked fuse 22 in the engine bay for the compressor but it is fine, forscan shows no DTC's..

Car is under warranty, but local ford dealers have turned me away and can't book it in until late May. Trying to get it sorted before Fraser next week.

Cheers

I lost A/C on my Ranger after some work was done on it unrelated to A/C but battery was connected and disconnected to a charger several times during this time.
On leaving the workshop I also had no A/C and thought the workshop had popped something due to the connecting and disconnecting of charger.
Had the same indications as yours with all buttons working, etc.

The short drive from workshop to local coffee shop for lunch on my way home didn't see it working.
After about 30mins highway driving (after leaving coffee shop) it suddenly started working again.
