Firstly, thanks for reading this....
I'm 17, jobless, typical lazy teenager. I have a handed down 1994 S10 Blazer 4X4 that is nothing but trouble.
It was super nice when my brother fist brought it home, then when he got a new truck and gave it to me, I realized he ruined it in so many ways :[
Anyway, heres the list of issues that I'm having. I'm going by knowldge gained from the internet, so forgive me if I dont know what im talking about. In order of the worst to not as bad:
Battery drain
-Drains out completely over about 3-4 days
-Ruins the battery usually
-New Alternator
Power brakes gone
-Ive narrowed it down to the brake booster, vacuum air hisses out as brake pedals pushed
-Master cylinder is good, and the check valve.
Electronic 4WD Not working
- Lights on the switch dont light up
- No clicking noises like there should be
- TCCM fuse is good
-Deff NOT engaging
-Worked before last Winter, stopped working after sitting through the winter
Noteable things that might affect all that:
Rear window is gone (broke it), maybe that is why the battery is draining? no lights stay on though...
Instrument panel lights wont work, keeps blowing fuses
Under dash lights dont work either.
There is NO audio in it, so that cant be it.
Specs of the truck:
1994 Chevrolet S10 Blazer 4X4
Tahoe Package
2 Door
4.3 V6 CPI Automatic
THANKS

with the 4wd try checking the vaccum hoses and the vaccum actuator (located under batter tray). search on here for 4wd problems and u'll find quite a bit its common for the 4wd to go out on our trucks.
as for the power brakes i would say check the lines since u hear a hissing it sounds like there would be a leak in the lines somewhere prolly vaccum line.
for the battery i would say the altenator is bad even tho u say its new cuz the battery cant support the entire sysem for that long on the truck so obviously the altenator isnt recharging it.
hope this helps u out somewhat. and good luck w/ fixin it up

A faulty vacuum actuator would not cause the lights to not light up on the dash though... I would first check the electrical connection at the back of the switch in the dash. We have seen a few of these switches either just have a loose electrical connection or be burnt out internally, causing the same problem you are experiencing. Another thing to look at with the 4wd system is the electrical connection at the TCCM (transfer case control module) located behind the passenger side kick panel (in front of the door, under the dash). Sometimes the electrical connection can get moisture inside, corroding the contacts.
Anyway, on the battery drain, I would start by pulling fuses and testing the open connection with a test light. Do them one at a time, looking for one that will light the test light. When power is flowing through a circuit, a test light will illuminate. If everything on that circuit is off, it should not light. You should be able to narrow it down to a particular circuit and we can help from there, but wiring problems are never fun to mess with.

Thanks for the help. Can you explain how to do a test light? I get what I'm supposed to do with it, I just need the test light first ha. Im going to try getting to the TCCM again too, I tried a while ago but the cluster of modules wouldn't pull down (they were caught on something up in the dash). As for the dash light, do you think that would drain the battery, because I'm not worried about that problem if it isn't hurting anything else.
The brakes I've basically figured out, the line is fine to the booster, the booster just gave out.

^^Thanks
I found where to buy the test light for a few dollars, Im going to grab a new battery and find the drain, if I fail, we have a mechanic in the family who can pinpoint it. Ill also check the 4WD switch and try and check the TCCM connections. Ill post pictures if I need further assistance.

I didn't catch if you had the trailer package. If you do, you could check if the plug wires have been shorted. This would cause the dash lights to not work properly. It could be draining your battery also, although the fuse (trailer/aux) should have blown. I belive that is what fuse it is. good luck.

It does not have the trailer package as far as I know...
Im waiting on some more cash so I can get a multimeter to find the drain, battery, and booster. Cant wait to get workin on it, hopefully before it gets cold again here, weve had a warm 2 weeks in N. IL.

Hi,
you dont need a multimeter to find a battery drain.. all you need is a light bulb (1156 for instance), or a test light, and hook the light bulb in series with one of the battery terminals and the battery cable... solder a wire to the terminal on the 1156, and solder another wire to the ground of the bulb.. once hooked in series with the battery and your vehicle, the bulb will light up when juice is being drawn from the battery (ie. battery drain)... if it does light up, go to your fuse panel and start pulling out fuses one by one, until the bulb no longer lights up.... once you find the one that stops the bulb brightness, you just found which circuit is causing the drain.

You can do the same thing at the fuse box itself. Just put the wires to the separate sides of each fuse location.

That sounds a lot simpler, so I'll do it that way. I might go to Wal-Mart tonight and pickup the light and a cheap battery. Not buying a decent battery until I solve the problem. Suppose to be warm tomorrow.

Another easy way to check for the battery drain is to make sure everything is off ie: doors closed, key off and out, dome light off etc. After that pull off the neg. side battery terminal and then just touch it back onto the battery, if something is drawing power you will see an arc between the batt. and the cable. Not a sure fire way to diagnose, I'm sure some part of the truck is always drawing a little power, I tried this on mine and got a very very small arc.. almost non-exsistant and very hard to see, turned my dome lights on and the arc increased ever so slightly, if you get a strong arc something shorting.
