Fan is working, but light is not. Checked bulbs, they are all OK.

Are you sure the bulbs are ok.Visually it's hard to tell. all the time if they are bad. Be sure and check them with a meter and if they check out ok then you need to check for voltage with the key in the on position and lights on.going to the rear light assembly itself. Usually if its just one side not working it's a bad bulb. But that's usually not always. Good luck.

There are 2 fuses for parking lights left and right side. so it can be 2 relays. located in the box in the front.

the fan operates well . the light was out of work .there is something wrong with light bulb . you just change a new one bulb .
wall light

You mean only the light? and the fan is working? Have you checked the light bulb? If it's ok, then checked on the wall switch. If is also ok, then probably there's is something wrong with the wiring in the fan.. It's either a bad or loose connection

are they both on the same switch?
have you checked the bulb it self or the socket that it goes into?
have you checked the plug in the fixture for the light? plug the fan into the light socket plug to check and do the same for the light - plug into the fan outlet...
have you checked both the neutral and the hot for the light plug?

If one of the surface light bulbs burnt out it may have shorted out the control board. Take the control board out and look for a burnt spot on the board. It may be able to be repaired with a drop of solder or solder in a jumper wire. Or you can purchase a new board, which may cost more than you want to put into the microwave.

These are Dual Function Bulbs. They control the Parking Lights and the Brake Lights. This Bulb is Burnt out on the Brake Coil inside the Bulb. I have actually seen Bulbs that were Bad But you could not Tell by jast looking at them. It should be fine with a New Bulb. Please Rate My Response! Thanks!

Sounds like it was the main fan motor - that caused the lights to blow in the first place.

Isolate from supply, and get the fan motor checked out. If it is burnt out (inside) you will need a replacement.

Hope this helps.

First check the fuses,the switches, sometime corrosion can cover the contact and check also the thermal fuse.......
