Question about Chevrolet S 10

1 Answer

My 2002 s 10 will not go into 4 wheel high i have taken it to my local garage 3 times to fix it and they tell me they have cleaned the burs off the chain, and greased it, they have cleaned the corrosion off the transfer case module and lubed it and they have replaced the transfer case module. and each time they say it works fine for them. when i go to pick it up it will go in maybe one time then it stops working, it will not switch from 2wheel to 4high while in motion, but sometimes when i stop and put it in neutral and take my foot off the break it will go, then sometimes the lights on the 2wheel 4 high and 4 lo will all flash or all go out completely. any ideas. the shop has guarented there work so i am not paying for the last 3 visits but they arent fixing the problem.

Get them to check the detent shift switches on transfer case for correct operation as well as the one on the front diff for the shift on the fly unit, these tell the module as to what state it is in.
2H,4L or 4H.

1984 mazda rx7 fails emissions for not burning enough gas

What are the HC and CO readings? if it is not that far out, tell your tech to richen it up an 1/8 turn at a time. The factory starting point for the mixture screw should be 2 1/2 to 3 out from closed can go as much as 3 1/2. As long as the throttle plate setting has not been played with. If that is the case it will take a bit more to setup properly.

ABS light,most of the time, indicates a bad wheel speed sensor.
If you don't have an American OBD2 connected code reader or scan tool.
unplug one wheel speed sensor at a time,put a volt meter on the two wires,
set meter to HZ, and see if you get a decent output ,when turning the wheel
Compare, to what most likely will be 1 or 3 other good ones.
