Customer Question

I own a 1992 318i and whenever the air conditioner is on, the gauges on the dashboard periodically cut out momentarily (approx. 1 - 2 seconds) and then resume working. I have also had issues with the dashboard lights and the A/C switch.

I am sorry that you have not been helped yet. I just came online and saw your question

Ok, I will need the vin number in order to pull the schematics, but offhand without referencing them, it sounds like a short in either the ac control unit if it is an automatic climate control or possibly in the IP Cluster assembly

Hi Eric, sorry about the delay
The vin is WBACA32090AK62759 This morning the fault occurred without the A/C turned on. I wondered whether it could be the alternator / regulator?
