I know this subject has been well covered, but I couldn't find anything similar.
I am having an intermittent problem with the lamps lifting on headlamp flash - no problem until this week.
The headlamps wont lift on flash - unless the headlamps have been switched on and off by the master light switch, then no problem.
The master switch is new - well 18months ago when the car came off the road. I have no problems with the headlamp operation by the master light switch.
Tomorrow I will clean all the connector under the bonnet tomorrow, any thing else I should look at?
