So today, after fixing my blinkers that kept going out (short to ground) I took my blazer home. Went out to take the girlfriend out and low and behold there are now fifty million problems again. The gas guage bounces back and forth when you use your blinkers and when you move from gear to gear (automatic). when left at an idle, sometimes the idle will run so very slow. Even to the point where it will die. And to top it off, all of the sudden my window actuator for the back hatch stopped working. Lock and all. Also a wierd rattle is now undernieth the rig and it doesnt look like its the catylitic convertor so i dont know. Any ideas would be helpful.

There is a key grounding point on top the crossmember above the rear differential.
Some here have moved it to cleaned area just over the side and to rear where it can be seen. USe plenty silicon or dielectric grease when you refasten it.

Dont think that will fix your idle. Probably a sticky IAC. When it does that, try tapping it firmly.

 

Alright so I moved that ground and it didnt seam to do anything. I put a new acuator in the back hatch and it still isnt working. I hit that IAC and it didnt do anything. The car doesnt die but it just idles really rough. Radios still out but the fuses arent going out. Im rather confused and starting to think that Im gonna have to pay an electrician..
