My 00 have with the basic crappy no tach cluster and that annoyed the crap out of me, I like to see whats going on. I bought the thing with a bad 1-2 shift solenoid so I replaced both of those but thats a different story for a new day. Anyhow I found a cluster from a 2004 blazer w/ tach. Now my problem is the tach reads WAAAY faster then what the engine is really revving to. All the other crap seems to be working fine. Any ideas like pop the needle off and reset it? or could it be that mine was built on 7-26-1999 that it has all 99 electronics in it?

I'm also looking for a set of affordable key fobs for it if anyone has a spare or two for a decent price.

Any ideas and such are appreciated. I just don't wanna swap this to my fiances 04 dime and see that its normal or something worse, btw this cluster only has 111,333 miles on it. PS, my title is mileage exempt before anyone wants to bitch at me about that part of the deal. I just want a working tach.


Thanks from the old man who just turned 32 yesterday,
Don

Oh and I now people are gonna want pics so...well that didn't work, sorry if they are huge.

 

Welcome Hoosier! But I have no answer

Fixed it, I installed a 00 blazer cluster today and it reads dead on. It turns out that I needed a cluster from a 2000 blazer/s 10.
