I have a sensor for my dash lights, they are not turning on at night, is there a fuse for it maybe? I have a 1998 Chevy Blazer 4wd

fuse or relay. bad wiring

It's a short check the useable links

There's been a lot of problems with the 4wd systems on the blazers of that vintage. The only sure way to track down the cause is to have the system scanned. Some of the most commom causes are: the switch in the dash, - the control module, - the transfer case . There are other issues if it has auto 4wd as the ABS system is tied into that system to activate it when the sensors sense wheel slippage. If your blazer has the auto 4wd funtion and has a ABS light on, it could be in the ABS system.
IF you could get it back into 2wd, you could pull the fuse to the 4wd to dis-able untill you have a chance to have it scanned.

electric dis/engage motor on the transfer case is not working check connections.check ALL fuses under dash and hood

Did you recheck to see if you plugged the speed sensors back in. The speed sensors are built into the wheel bearings on the 4wd models. If you did plug them back in, then one of you new sensors might be bad.

I have a 1998 Chevy Blazer, 4.3 ltr... in the fuse box i am trying to locate the fuse for the dash board lights(light behing the speedometer and the radio lights and the lights that illimunita the heat/ac control kmobs... need help,any ideas and or good sites to go to ? thanks need info asap...its jan 25 2011 5:15 est...

yes its at the rear of trans

switch, 4x4 motor, 4x4 module can cause the lamp to come on need the code most parts stores will tell you code with out charging a dime

my son has one and his did that and it was a fuse he put a new one in and it is working good now

I would say that maybe the dimmer is turned down or the dimmer switch is bad
