I have automatic headlights on my car so never normally have to make any adjustments with them, but I recently noticed the headlights weren't working at all, only the sidelights were working. The headlights were switched to automatic, I then changed them to the "On" position, but that made no difference. The strange bit is that if I switched the headlights to the "Off" position the headlights turned on, but I lost the rear lights.

I have been told it may be the control module, which is a very expensive fix so I was hoping someone could suggest other options to try first before committing to a costly fix with a garage.
