I’ve got some electrical problems I could use some help on. Instrument cluster back lights don’t work. Fuse #10 (Instrument Cluster) is good and getting current. I pulled the instrument cluster and unplugged both plugs just to make sure they were seated. Plugged back in with no change. Turn signal indicators work, check engine works, et Al, but no backlighting.
Fuse #1 was glowing and I removed the fuse quickly. It was extremely hot and blown. I put another fuse in and the sequence is it gets hot and starts melting the plastic, then blows the fuse, but keeps glowing and melting the plastic. I cleaned the fuse blades and fuse holder as well as I could with no change. When I put a new fuse in I see a spark in the input side and it Immediately gets hot.
Fuse #4 (door defeat) is good, but no current passing through the fuse (is this normal?) When passenger door ajar there are three sets of double beeps and then nothing. When driver door ajar it beeps as normal till the door is shut. Any ideas appreciated.
I’ve read that:
If the tension in the fuse holder is not good then the connection will not be good, and heat will build which can blow the fuse.
Aluminum oxide can also build up on the fuse blades causing a poor connection with the same result.
Not sure how to fix the tension in the fuse holder. I can get better fuses with a thicker blade for a better connection, but the original fuse was a good fuse. Some of the others I tried were lower quality Amazon bulk.
