I purchased a cluster from a 2001. It looked the same externally, but when I installed it the fuse tripped.
There are three circuit boards on the inside of the clusters. One under the gages and two sandwiched on the back side. The outer board on the back side was about half the size on the 2001 compared to the 1999. The board under the gages was different on the 2001 due to an additional "check gas cap" light. The center boards looked identical on both the 1999 and the 2001.
I installed the 2001 center board in the 1999 cluster and reinstalled the original cluster. All the gages work fine now and the fuse doesn’t trip.
Thanks for all your help. |
