Mystery to be solved
Good afternoon,
Have a mystery to be solved.
07 Avalance, 106,678 miles. Week ago the passenger low beam headlight went out. Now, I have had this Avy since brand new and have replaced many lights in the headlight buckets, hell got it now to NASCAR pit time. Being OCD as a I am I replace every bulb, both sides. I did this yesterday, after doing so I now have no parking lights, brake lights work, turnsignals work front and rear work. I do not have DRL or running lights in the rear. I do fully understand how DRL and the auto headlights function. After checking the fuses in the fuse box under the hood fuses 25 and 26(Driver's side park lamps and passenger's side park lamps) were blown. They were replaced with 15 amp, after being replaced the problem still exsists. Fuses in vehicle are good, relays are good. Have checked headlight bundles for shorts, no issues. All the bulbs that were replaced are what suppose to be. What am I missing?
Any and all help would be greatly apreciated , wife needs the truck on Monday for grandma duty and as we are in Alaska it's dark when she leaves and dark when she returns.
