Interesting Denali/Escalde Cluster Issue

[Diller]

I installed a Denali cluster in my '99 Yukon Monday night. I was checking all of the bulbs to make sure all were working.

Upon doing the initial key on cycle, I noticed the "Service Engine Soon" light doesn't illuminate. I pulled the cluster out and snapped in the old cluster. The old cluster DOES light this up. So I switched the bulb from the old to new cluster. The SES light still doesn't light up.

Any ideas??

bad connection on the back of the Denali cluster maybe?

The printed circuit looked fine......but then again, that doesn't mean anything.

have to agree you have a break in the board somewhere. or a damaged pin on the connection

ya but since the old cluster works and the bulb from the Denali cluster is fine then its gotta be somthing in between the connections behind the cluster to the connections to the bulb doesnt it? did you try the cluster in a different truck?

Not as of yet. Once I get to my mom's this weekend, I could try it in her '97 Tahoe Sport.
