How to replace the seat belt for the driver or passenger on 2003 Cadillac DeVille?

The process to replace a seat belt for either the driver or passenger starts with removing the front seat back trim cover while safeguarding against SIR Caution. Afterward direct your force upwards until the rear segment of shoulder belt post trim comes loose then pull upwards on the end of the shoulder belt tower close-out ring to break it free. The seat back cover J channels must be removed first from the top and both sides of the seat back. At the same time you remove the front half of the shoulder belt post trim by uninstalling the 3 fasteners. First detach the seat cover from the upper trim retainer then remove its two fasteners. First separate each upper trim retainer half from the seat alongside marking the seat back frame above the upper trim retaining bracket for later reassembly alignment purposes. Detaching the post from the upper seat belt retractor enables removal of the retractor from the frame within the seat. Unlock the push pin retainer at the front of the lower seat belt retractor trim cover and free the rear of the trim before removal. Free the tabs to detach the lower seat belt guide from the lower seat belt retractor followed by taking out its fastener. Remove the upper rivet from the lower seat belt guide bracket then rotate the bracket for clearance when removing the lower seat belt retractor. Remove both seat belt retractors together with the associated trim assembly from the vehicle. Before mounting the lower retractor, check that the seat belt remains untwisted then position the mounting stud correctly and secure the fastener to 55 N.m (41 lb ft). Put the seat belt guide bracket against the frame position then apply a fresh rivet while adding the lower retractor seat belt guide cover and lower retractor trim cover . Use the push-pin fastener together with the upper trim retaining bracket while aligning them with the mark on the seat. The seat back frame upper cross member functions correctly when the upper trim bracket stands parallel to it. Install the upper shoulder belt retractor onto the seat belt roller without being twisted then position correctly both the anti-rotation tab and the upper trim retaining bracket before securing the fasteners at 55 N.m (41 lb ft). Attach the upper trim retainer to the upper shoulder belt retractor by tightening its fasteners to 1.4 N.m (12 lb in). The upper trim bracket along with its fasteners need to stay away from blocking any movement of the upper seat belt retractor. Complete the assembly by covering the trim retainer with the seat back cover before installing J channels to the seat frame and attaching front half shoulder belt post trim with fasteners tightened to 1.4 N.m (12 lb in). Finish the assembly with shoulder belt tower close-out ring and rear half of shoulder belt tower post trim cover and front seat back trim cover while checking seat belt retractor function.
