Default Air Con showing *ER*..whats does it mean?

Switched on the aircon and it looked as if it was working then *ER* shows, not on IPK display but on the aircon disply, ran it for a few seconds and it was blowing hot air so switched it off.

Even when switched off *ER* stills shows
What does it mean?

Just got the radiator replaced and also they had the centre console out checking out an airbag fault so wondering if the garage did not put it all back together right
also charged an arm and a leg for those repairs and just do not want to have to put the car in again and get another big bill

Has been in the 40's this week, so running the aircon on cold for 30 minutes in the morning going to work and 30 minutes in the evening returning so i do not think i was over doing it.
Any advice appreciated

Hi Joe,

I've never heard of 'ER' before. The air conditioning has it's own limited diagnostic system but this shows 'FC' in place of the left-hand temperature display and a numerical code in place of the right-hand display. You could try activitating this manually to see if it produces anything:
  • Press and hold the AUTO and air distribution buttons.
  • Turn the ignition switch from 0 to II.
  • The audible and visual warnings cycle on and off whilst the ATC ECU runs the diagnostic check.
  • When complete, either FC and a code is displayed or the system returns to normal.

In any case it would seem extremely likely that the garage has forgotton one of the connectors when reassembling the console. Take it back to them without delay.

Simon.

Thanks Simon
I knew you'd have an answer
It ran ok for a week after the garage worked on it, I'm hoping it's something they did wrong so they fix it rather than my air con has died.
Can you clarify the test procedure?
Press the auto button and the button that changes the air direction from feet to face for example?

I found that the errors are related to the left and right solar sensors
any idea where they are?
and what i'd need to check/fix?

The solar sensor cables are in one of the two connectors in the back of the ATC panel and a couple of connectors behind it, Slate/Orange, Slate/Purple, and Orange/Yellow. I would think one of them has been disturbed when they had the centre console out.
