Installation
The regulators are model specific: they bolt into the factory mounting holes and run in the stock window channels. Wiring is 30 amp — most of our harnesses come with an in-line 30 amp fuse, and a circuit breaker works too. Feed the windows straight from the battery, from a spare slot in the fuse panel, or from the key-on side of the switch. The ground has to come from the master switch, and each motor takes power on one pole and ground on the other, not to the motor case; swapping those two wires reverses the direction of travel. In most cases no relay is needed.
For lubrication, use a high-temp automotive wheel bearing and chassis grease such as NLGI grade 2 on the regulator gear teeth and roller tracks, and stay away from older soap-based lithium grease, which sets up hard in the cold. A few drops of lightweight oil at the pivots lets the bronze Oilite bushings run smoothly. 3M silicone spray helps break in the fuzzy runs and weatherstripping, and dielectric grease or Tuner Lube on the terminals keeps moisture and corrosion out.

Common questions
Do the doors have to be modified?
No. The regulators are model specific, so they bolt into the original mounting holes and run in the stock window channels. The door looks and works the same from outside.
What is in the kit?
Two front door regulators, left and right, plus two new ACI motors. Switches are a separate choice at the top of the page - order a switch kit and the conduit is included at no extra charge.
Is there a warranty?
A lifetime warranty applies with a copy of your sales receipt or invoice, so keep the paperwork.
How do I know it fits my truck?
This part is listed for 1973–1991 Chevy and GMC Blazer, C10, C1500, C20, C2500, C30 and others. The full year, make and model list is in the Truck Compatibility tab on this page. If your truck has been modified, or you are between two of the year ranges we list, send us the year, make and model and we will confirm the fit before you order rather than after.
What if it is not right for the truck?
You have 30 days from delivery to request a return. The part needs to come back new, uninstalled and in its original packaging - once a part has been trimmed or welded it cannot go back. Return shipping is at your cost, and we ask that returns come by Canada Post. Made-to-order, sale and clearance items are final sale. The full terms are on our returns page.
Can I install this myself?
It is designed for an at-home install. Read the fitment notes and the Installation tab on this page before you start for anything that needs drilling, trimming or welding, and where an installation guide or video exists for the part it is linked there.
