Hello. I saw on this site...
...discussions about using a tccm from various GM compatible vehicles across a few years. When shopping for a replacement, I get conflicting info. There are used ones that show my 2002 as compatible but if I go to a GM part site, it says what I'm looking at is not compatible and it directs me to something else. I pulled the wiring schematics and while I do see some differences, they are wire colors and the atc fuse amperage. The fuse in mine is a 25a and the fuse in the 06 on the diagram is a 30a. Perhaps this is why not compatible?
Mine: 15085386
Suggested replacement: 12590220
Found: 24233673 from 2006 TB listed by seller to fit 2006-2009 TB and then similar date spans for Envoy, Rainier etc ------ I found other sellers of the same part number marketing it to fit my 2002 all the way through 2009. The GM part site for compatibility and replacements says it will not fit and points me to the suggested replacement above.
Is this amperage part of the issue and should I stay away from this replacement part?
Compatibility of different TCCMs for 4x4 Envoys, Trailblazers, etc.
Hi, all. I have a used 2002 Envoy SLE (4.2 I6) that is in great shape, except for no transfer case control (surprise surprise...) At any rate, I get the classic "lights on control switch light for a few seconds at start up, then turn off, with check 4WD light on dashboard". So, the switch...
