I just repaired the power window regulators on my mother's 1994 Mazda B4000 pu. After removing the door panel, unplug connector, secure the window so it so it does not drop, remove the pop rivet holding the regulator motor, locate the third bold and drill a 1/2" hole. This is necessary to access the third mounting bolt. Unbolt the 3 regulator motor bolts. Remove the regulator motor. Remove the c-clip from the gear shaft. Use a pair of small needle nose pliers to squeeze the cover retaining pin and push it out. Remove the small gear and cover. Wipe up old grease. Inside you will find a large nylon gear. If the gear teeth are in good condition, you just need to replace the window regulator gear plugs. Make sure all broken bits are removed. Use some white lithium grease to lube the gear teeth and center shaft. Do not get any grease in the area where the plugs rest. Reassemble in reverse order. A 1" long 1/4" bolt with self locking nut will be used to replace the rivet. A washer should be used under the head of the bolt. Make sure to the bolt is on the panel side the nut is on the inside of the door or the panel will not properly. The Window Regulator Gear Plugs NAPA part number is 665-1524. The total to do two door was $17.38 plus tax.
