first off my interior lights are having a few problems.middle one has never worked and the ones in the mirror have decided to stay on even with the doors shut but i dont know why,ive had to dissconnect them from the mirror to save the battery,is there a relay for these?treid the bulb in the middle one but still doesnt work.
also my heater has just stopped working checked the fuse but it is ok,is there a relay for this or could it be something else

any help would be great as im new to these cars

cheers

Your mirror contains map lights which are also controlled by 2 switches mounted on the bottom.

Dome light ▬ find out if the hot or ground is missing.

Remove it and make sure the wiring is still connected.

If so trace it back to where the break is ▬ easy fix.

Heater blower motor ▬ if none of the speeds work connect 12 volts directly to the motor to see if it’s good.
