I've replaced the front fog lamps, it looks much better than the gaping holes that were there when I bought the car. How and ever, only the driver's side fog works, the passenger side bulb is not open circuit says my multimeter, but does not light up, even after a squirt of WD. Is there anything typically Micraesque I should look for? Haynes seems to say the left side fog is earthed at the rear lights, oddly enough, but they work fine. Any ideas? Thanks.
