So i i found a blazer for sale and it seems right i have a few issues with it the console doesn't work temp oil pressure and gas guage there is absolutely no oil pressure the gas gauge might turn to the right then back to empty and the gas light comes on then the temp gauge might show where its at then go back to 0 i need some help i did swap out the cluster for my spare one same thing happened to that cluster but not as frequently 4wd does not work but i think its cause a missing vacuum line that i need to find and my biggest issue is the very poor job someone did putting an aftermarket radio in it there was a wire going from the radio and directly through the dash and into the interio fuse block i can get pics later but if anybody can help me with any of these issues i can get pics tomorrow and i'm pretty bad with using forums like these forums noob lol but with the radio it only gets power from that fuse and someone cut the stock connector out i guess spliced it back with the radio kit so i can't make heads or tails of it but right now my biggest problem is the cluster and radio right now getting 4wd to work i'm hoping its just that vacuum line but i dont remember where the vacuum line goes remember please i am forum noob

 

That is one long sentence.... wasnt able to do it in one breath.... wasnt able to stay focus enough to read the whole thing...

but I would purchase it unless it was only a couple hundred, as it might take a few to get the problem worked out...

 

well my 1st concern is 4wd is not working but i found that the vacuum line that runs across the top of the engine through the throttle body and stuff is not connected but i can't remember where that vacuum line goes i have an 01 S10 and i know right where it goes but i'm not sure if it would be the same from 01 to 04 i'm sorry if i kinda jumbled all over as i said i'm not used to using forums like this lol

 

Jay Snow, please use punctuation in your posts. Lots of people get put off by long, run-on sentences and will not reply. Just the way things are.

 

Tell me if this is a correct run down of your issues.

The following things are not working correctly or at all

1. The gas gauge
2. The oil pressure gauge
3. The temp gauge
4. 4WD (possible missing vacuum line)
5. Poorly wired radio?

Here is some other things that would help people troubleshoot your issues.
1. Year
2. model
3. how many doors (if it is a Blazer, Jimmy or Bravada)
4. auto or manual
