Hey guys and gals
I have a 03 caravan sport the foglights aren't working I changed them and checked the fuse and relay I put the air con. Relay in there but it still not working can anyone help me please

 

Remove the relay. Jumper contacts 30 and 87. Lights should turn on, keys in your pocket. That proves the output side of the relay circuit is good. It also means the problem lies in the control side of the relay circuit meaning the switch, BCM, IPM, FCM and the PCI data bus are all suspects. Anything that plays a part in supplying the ground to the relay coil.

 

You should be able to hear the relay click when you hit the fog light switch.

 

Thanks guys it was the switch.
