Can somone help me I just did what no blazer owner wants to do. I changed my heater core. After 2days and countless hours I survived yet not without its problems after. I put the dash back in and I believe I missed a plug my thermostat gauge, my fuel gauge, my 4x4 wont work and my battery light is on as well as my ABS light are on. Can somone tell me where this plug is before I go back into Ole blue and tear her dash apart again.

 

Sounds like you might be missing a ground wire somewheres. Where, I can't say. But I'd tear into it looking for a thick black wire. Maybe check fuses before you really get into it. Maybe you blew one in the process of your repair? Start with the simple stuff.

Good luck!

 

Yep sounds like thats it I have to look around this weekend and find it cause we just had our first snowfall last night blaaaaahhhh and I have no 4x4.

 

Yep found it Thanks B Kewl for the start, just under the steering wheel I noticed a black n green wire with a small plug. hmmm its plugged in well lets check it, then snap it wasn't plugged in all the way yeahhhhhhh an easy fix for once lol
