Report 89 convertible window regulator in 1984-91 Avanti Posted June 15, 2021 On 5/24/2021 at 1:22 PM, Swampboy said: Motor Window World repaired mine recently. No broken parts, apparently just frayed cable/guides replacement and cleaned motor, $225. Here are pictures that Jim S asked for in his other post. Yep, it's a bear to get in and out - removing the two screws that hold the motor onto the frame (not motor to gear hub) is the key. Not necessary to remove motor, just slide it out of the way to clear bracket and window slot.
