Tailgate Regulator/Motor Assembly w/Relay (NO MORE CABLE PROBLEMS), 73-91 Blazer

The ultimate fix for your slow electric tailgate window and faulty motor cables. NO MORE CABLE!
Kit includes: 1 tailgate regulator, 1 new ACI motor, 1 relay.
This all new tailgate regulator will replace your existing manual regulator or your factory power regulator. The new regulator will eliminate the problems associated with the old cable driven motor. The new tailgate power window regulator is completely gear driven.
You can add a switch kit at a discount.

If you are using old style 3 pole switches, a special pre-wired relay is provided to reverse the polarity at the motor. These do not increase amperage,
they just swap the ground from side to side.

ACI Motors are Reverse Polarity
This means that the ground for the system must come out of the master switch. There are 2 poles on the motor - to make it operate,
you must put power to one side then ground to the other side - NOT to the motor case. This will result in the motor turning in one direction.
By swapping the wires from side to side, the direction will change.

Fuses or Circuit Breakers - 30 AMP
Most of our harnesses will come with an in-line 30 AMP fuse. If you prefer, a circuit breaker will work too.
You can hook your windows up to a varity of different power sources.
Some options are: Straight to the battery (Windows should not have any battery draw when not in use).
Find extra slot in fuse panel - tie in using the supplied fuse.
Pull power from the key-on side of the switch

Relays
In most cases, you will not need to use a relay to boost amperage to the motors. The switches and wiring we use can handle the amp draws.


Grease & Oil
1. On the regulator gear teeth and roller tracks, we recommend using a high temp automotive wheel bearing and chassis lubricant.
NLGI grade 2 is one option
2. Avoid the older soap based lithium grease - it sets up hard in cold weather making the windows harder to move
3. A few drops of light weight oil in the pivot points will allow the Bronze Oilite ® bushings to work smoothly and reduce wear.
4. On fuzzy runs and weather stripping - some 3M Silcone spray can help with break in
5. Use Die-Electric grease or Tuner Lube on all terminals and connections. This protects against moisture and corrosion.
