Re: 2003 chevy astro blower motor
The wiring on your 1996 Astro is different from the 2003 explained above. Here is how to bypass the high blower relay on your 1996:
On the add-on relay:
Terminal #86 goes to ground.
Cut the orange wire at the blower resistor and connect it to terminal #85.
Cut the red wire at the blower resistor and connect it to terminal #30. You need to use 10 gauge wire to extend it.
Splice a 10 gauge wire on to the red wire that goes to the blower motor, (do not cut the red wire) and connect the other end to terminal #87.
