so my batt voltage has been fluxuating, and my gas guage also, im getting scrambled numbers on my milage and MPH/MPG reader above the rearview for a second when I first turn the truck on, my wiper motor is extreamly loud and does not spray...I am going home and checking fuses....seems like since my cd player started spitting out CDs and giving me an ERR little things have been going wrong...seems to be always running...maybe draining the batt? ARG blazer guys? got any ideas?

as of right now there are several things bothering me
FYI battery is new...maybe 2 months old

1.CD player not working, err and seems to be running while not in use
2.steering wheel making a rubbing almost like if you rub a balloon noise while making right turns only
3.batt voltage and gas guage fluxuating
4.starting up weak after turning it on a few times during the day (starts great first thing in the morning)
5.wiper fluid does not spray but it SOOOO loud
6.AC compressor not working (turns on and off and on and off while air is on, air is not getting cold)
7.ac compressor hose has a crack where its bolted to the compressor and is leaking.

ARG...I think there is more but cant think right now....this is not so fun anymore.

 

i can say # 6 is normal the compressor should turn off and on but it does sound like you need a recharge if you aren't getting cold air , however fixing the leak first is suggested.
#1, and 3 sounds like maybe a bad ground or electrical problem,,, I am sure members with the same issues will chime in

 

so I went home and took the radio batt fuse out....when I put it back in it sparks and all my gages jump! when I changed out my cap and rotor and was hooking the batt back up they were jumping all over the place WHAT THE HELL MAN! can I just leave this fuse out because I am sure its part of the issue.....help!


NONE OF MY GAUGES WORK WITHOUT THE FUSE IN! WHAT THE HECK!?

 

I had the same problem with my gauges shortly after I bought my truck, and it was a shorted wire in the steering column (sorry, don't remember which one).
