🔧 Grand Cherokee - Rear Window Regulator Replacement

Replacing a rear window regulator means removing the rear door trim panel, securing the glass, swapping the regulator assembly, then reassembling and testing the window. The exact steps (and bolt locations) vary slightly by rear door side and whether your replacement includes the motor.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours (per door)

• If the window is stuck up, you’ll still be able to release the glass after the panel is off, but you must tape the glass securely.

Before I give you the exact bolt-by-bolt steps for your A4 rear door (with correct fastener locations), I need 2 quick details:

• Which rear door are you repairing: Rear Left (driver side) or Rear Right (passenger side)?
• Does your replacement come as a regulator with motor attached, or regulator only?

Reply with “rear left with motor” (or similar) and I’ll lay out the full procedure.
