1997 Dodge Intrepid 3.5
Check negative supply which connected from battery its well connected or not hope there is loose connection issue
Thanks Ajmal. Battery cables are clean and tight.
Then what's the result
I will test the circuits later and then take the next step. Thanks

If you told us what make , model an year we would be able to say for sure . Could have a BCM - body control module involved in making these thing's work . Need to look at a wiring diagram to know for sure .
Testimonial: "It's a 97 Dodge Intrepid 3.5 engine. Someone just told me it could be the multifunction switch going bad."
Sorry, forgot to add make/model. It's a 97 Dodge Intrepid 3.5
Well hammer the thing to do is check the circuit with it powered up , See where B+ voltage is missing so you know for sure . At the headlamp switch connector 1 pin #7 red with white stripe wire should have B+ voltage .Next with headlamps on pin#6 connector 1 lite green wire should send B+ voltage to pin # 7 at the headlamp dimmer switch. With headlamps on low B+ voltage should be present at pin # 5 at dimmer switch ,this sends B+ voltage to fuse # 16 a 15amp fuse. in the under hood fuse box. On high beam fuse's 11 & 12 both 15amp in the same under hood fuse box. With headlamps on ,low or high the voltage goes through the fuse's I mentioned to the headlamps an through to ground . Right headlamp G-105 , left G -102 .
Do you have a DVOM - digital volt ohm meter , you can buy one at parts store , harbor freight etc.. for under $20 . You can watch some videos on you tube on basic automotive electrical testing , how to read a wiring diagram . In the automotive repair business this is how we find out what the problem is ! we don't go by someone saying the multifunction switch could be going bad. If the lights don't work , something is bad.
Thanks, I will get the DVOM and study how to use it and test the circuit before changing more parts.
