2005 Honda CDTI headlights and aircon

[Noblebenn]

I have a 2005 CDTI accord and it loves blowing headlight bulbs. Both sides blow, once together but usually one at a time and seems to happen every other month. Car is driven for only a couple of days a week and stands for a few days in between. Has covered 160k and drives wonderfully.

My air con is blowing cold and have had it in to the garage and they have said it seems to have an electrical fault between the switch end in the car and the air con unit. Nothing shows up on diagnosis so it would be case of start investigating until the problem surfaces.

It has been fully regicide and the clutch etc are all working fine.

2 individual problems but if electrical could they be related in any way or has anyone any suggestions for places to investigate etc?

Thanks
