hey all does anybody have any info on if there are any other years that chevy used the same tccm in the 4wd blazers? im hunting a tccm for my 94 s-10 blazer.

 

Hollander Interchange report for TCCM:


S10/S15Bla/Jim 92-94; (right side dash)
S10/S15/PU/Son 92-94; (right side dash)

*Service number match recommended*



Hope this helps.

 

I've been having a hard time figuring out why I don't have lights on my 4hi/4lo switch and why 4wd won't engage.

Just curious as to what has led you to determine that the tccm is bad?

i got this from these guys. the reason i believe its the tccm is when you engage the 4wd you can hear an electric "click" from the passenger side of the truck. well it clicked quite a few times when both lights were blinking and i kept trying to get it to engage it and then there was nothing from that area, i checked the fuse for the tccm and its good, and everytime i start my truck both lights on the switch come on, so im getting power to the switch.

i think when i was trying to get the 4wd to engage over and over when it wouldnt engage, i think i fried the tccm since there is no "click" anymore. i hope this helps you a little.
