Air Con showing *ER*..whats does it mean? - Page 7

allegroman · 16th February 2011, 21:51

After messing around with my centre console (removing everything to wire a power socket into the existing lighter) I've got the double 'ER' message and a non-functioning rear demist... and straightaway I find the relevant problem described, and solved, here

Now I just need a chance to check out the fuse when its daylight/not raining

Glad it's not as warm as down under...

Wow! what a thread... Great stuff to learn from this.

I remember when I lived in The Blue Mountains during the bush fires in the early 90's. Got to 47c a few times even up in the mountains.

Fun when it eventually rains and everyone runs out side to cool off. Can't see that happening in Shropshire.

Air-con is a must in Oz.

My car has been fine - until I started it today.
I have the Er message on both sides of the climate control display. Like this error, if I switch it to econ it doesn't error. The led on the rear demist does not light. The indicators and main beam, lights etc all work, but nothing lights up on the dashboard and the indicators don't flash or make a noise on the dash.
I have checked fuses 4, 5 and 11 and they look ok.
Whether or not it's linked, but we had very heavy rain yesterday. I've checked the drains and they all seem clear and dry, as is the carpet in the car.
Help !!

Do you have parking sensors?

grantkwilson · 28th August 2015, 18:46

I don't. It must have been linked to the heavy rain but I couldn't find any damp patches or puddles !

Hi,had the ERR message on the heater control display on my launch car.Originally thought it was caused by having the battery out of the car for a few days on charge due to the alarm going off caused by a flat battery and due to no battery getting software mix up.I found the battery had discharged by noticing the sat nav disc holder was not powering down.Previously had no problem with it. Took the sat nav out to disconnect it and found a slight amount of water in the housing bracket and where the two connectors plug into the back of it.Water had just got onto the PCB inside on the power connection.Reading on previous posts decided worth a try and cleaned up the PCB with a brush and left it out in the sun to dry out.Seems I was one of the lucky ones as have put it all back with no ERR message and sat nav now powering down.Water ingress was caused by the chrome side trim.Ironically had previously done the other side as that is where I saw water ingress.Presumed I never did the other side as that had always been dry.Probably turning the car around and altering the lean angle that is how water crept in on that side.It was only a miniscule amount of water but enough to give me the ERR.If you do not have sat nav then all I can think it is down to a short somewhere else.Another area I looked at trying to work out why my alarm had gone off I took my bonnet switch out and found the two wires had been rubbing and were shorting or about to.Regards Ry...

Hi
I went through a massive puddle on Friday (nearside) I think I may have water ingress behind wing liner.could have a bare wire due to chaffing on the loom?

Just been looking for a fix for my A/C when I found this, same problem with ER both sides. It was fuse 34 in the end but a reverse connection to a new powerfold mirror was what blew it! Who would have thought operating a mirror could cause an error message on the heating when selecting demist.
