Hi ercooper75/ Welcome to the forum. I repaired a few of these years ago with mixed success. There is a fuse resistor on the circuit board that develops intermittent solder connections due to the heat it generates. Cleaning and resoldering it solved the problem on a couple of them. Others had to be sent in for repair and came back with a note of service performed also related to bad connections. I've been in tv / vcr repair for 35 years and I know what to look for as far as bad connections. I could not see any resoldered connections that I missed and I could not find any evidence that parts were replaced, yet I can't argue with the fact that they worked fine when I got them back.
By invitation of the former owner, I visited Downtown Radio of Denver about 10 years ago and met one of the technicians who regularly worked on those clusters. Real nice people. I never was allowed to buy the service manual for these units but they did sell me a lot of radio manuals. Unfortunately, the new owners of the company won't sell me manuals anymore. You also might try United Radio in New York. They have a very good reputation. Another company I've dealt with in the past is Instrument Sales and Service in Kent, WA. They have other locations too including Denver. Also look at Hunt Electronics, I believe it's called, in Michigan. I'm told my local Chrysler dealer sends warranty radios to them when they don't use me.
