I have a 1998 chevy blazer (s-10) 4.3L 4x4 it keeps blowing the #15 (10amp) 4wd fuse, if you put a 10 amp fuse in it will blow the minute you turn it on ,then we put a 15 amp in it seems to do it when you shift into Drive (we put a light on it and when I back out of the driveway it stayed lit but the minute I put it into drive the fuse blew light went out? still running and everything can't figure it out

The links lead me to believe there are interchangeable. In fact this page confirms the compatible models

1999 - 2006

fuses blow from a dead short after then
check the wiring for bare wires , faulty unit , burnt out actuators

Test the circuit for that fuse and correct the short. Sounds like you have a parasitic draw on the circuit

Hi Corey, Sounds to me as if there is a problem with the motor which engages the 4X4 hi lo system. It could be something is jamming the thing from correct operation or a burned out motor. Regards John

will work might have a few sensors with different plugs but shouldnt be to bad

need email address to send diagrams, need to know what parts of electrial you need

There is an electric actuator on the front axle that engages 4WD. This part commonly fails resulting in no 4WD. Unhook the electrical connector to this part and see if heater still blows fuses. If It does not blow the fuse, the problem is in the actuator. If it still blows the fuse then it could be in the wiring. Buy a repair manual and trace the wiring schematics.

Need to know what the fuse goes to. Then a solution cn be found.

Your 20 amp fuse will not blow if glowplug wire shorts. each plug draws 15 amps which is 120 amps total.I think there are in line fuses for them. Try to wring out where each output from the fuse goes, disconnect all and reconnect one at a time till it blows.That should point to your problem process of illumination! Good Luck!!

1997 blazer put car in park shut it off but, key won't turn far enough back to come out
