1994 chevy blazer s10 v6 electrical issue

Although it is possible all the soliniods are bad that usually is not the case.

It could be a problem at the factory relay module. The module is controlled by the 3 wire switch. The ORANGE / blk should meter at 12v constant...when the switch is in one position it should send 12v+ to the blue wire..in the other position to the black. When the switch is at rest the blue and black will read neg or close to it, this is normal.

Find that "clicking" noise..should be underdash somewhere..that is the factory doorlock relay..sounds like the problem lies there since you only hear the clicking in one position. If everything looks good with it and the plugs are in solid with no corrosion etc. you may need to replace it..or make your own setup by using 2 relays for "5 wire" doorlocks (easy) and they will work again.

Good luck

oops..well not that it really matters in the scheme of things, the doorlock "motors" are actually actuators...not solinoids..technically a solinoid only does work in one direction...such as a trunk release or a door release when shaved doors handles are done etc., whereas an actuator does work in 2 (push/pull) as with doorlocks.

Just though I'd share that tidbit.
