I recently noticed one of my fog lamps were not working one night so i pulled the working bulb/soldered to wire off and plugged it into the other side of the non working fog lamp to test to see if its just the bulb, and of course it was thankfully. So i go and put the working fog lamp back and when i go inside the car and hit the fog lamp button to insure it was back to working again, all i hear is a buzzing noise coming from the the dash and neither the fog lamps work and one of my high beams don't work now. could it be a coincidence that i had a bad high beam lamp at the same time also? What could this buzzing noise be? Help?

Re: Catera - Buzzing noise when turning on fog lamps.
Maybe it's the K134 Multifunction Relay. It's not just one relay but an assembly of relays that control various features. Not sure if the Fogs are included but it's worth a look-see. They're notorious for developing cold solder joints. Inspect and resolder any suspicious joints before spending on a new K134.
