2005 Safari both low beams work; the right side high beam does not work. Cleaned contacts at the headlights, checked wires into the harness, cleaned the chassis grounds. Checked the headlight relays and fuses. Swapped the headlights. Replaced the Multifuntion switch / wiper / signal / hi-low switch.https://www.ebay.com/itm/GM-OEM-Windshield-Wiper-Switch-26108513/282021368369
Brand new in the wrapper. Replacing the Multifunction Switch is very theraputic..... plan on a 12 pack and help from someone with small fingers.
Sadly, it didn't fix the problem. Both low beams work; but the high beam on the right side is still not working. Voltage at both headlights are the same reading; both reading match for the low beams and both reading match for the high beams respectively. 12 volts on the pin on the right.
WTF.... Any ideas?
