I have a 05 XC90 with some issues on the lights. The drivers side headlight parking lights are not working with good bulbs. The passengers side headlight side parking light does not work but the one by the turning signal does. As I switch the wiring harness on both sides, the side that was not working seems to work. Has anyone ran into this problem before?

 

My 2006 XC90 V8 left rear turning signal light bulb is malfunctioning intermittently. Sometimes the left turn signal does not work and there is a message shown on the dash saying the left light bulb is burnt.
I had it checked at a repair shop and they said there was no burned light bulb, but they replaced it anyway. However, the same thing happened again keeping the left turn signal inoperative for a few hours or days, when it suddenly starts working again. The light bulb was checked again and it is in perfect condition. The electrical harnesses were also checked for bad contacts, but we found no problem with them. Any suggestions about where else to look for to solve the problem?
