# SQUEAK AND RATTLE ITEMS (CAUSES AND REPAIR PROCEDURES)

The following information contains several causes of squeaks and rattles and how to fix them.

(1) ECM retainer not installed properly (right side I.P. tinny noise). See Figure 1.

a. Retainer not in hole. Remove hush panel, loosen two (2) level ECM bracket screws, reach hand up and reinstall pin in hole. Tighten screws and replace hush panel.

b. Lower screws loose. Tighten screws.

c. Retainer not tight on screw. Tighten retainer.

(2) ECM rattle (tinny sound behind glove box).

a. Remove the ECM.

b. Put RTV adhesive in the corners. The rattle area can be located by tapping the case and stopping the noise with light pressure.

(3) Antenna couple rattles against I.P. (hard knocking sound behind glove box).

a. Wrap foam around cable at couple (see Figure 2).

b. Antenna cable and courtesy lamp wires rattle. Tape wires to I.P. below glove box (see Figure 2).

(4) Panel between deck lid and rear window rattles, metallic noise in rear of car. Attachment screws loose or stripped. Replace these screws with larger diameter screws.

(5) Steering column squeaks against I.P. Reposition column and shim if necessary.

(6) Heater hose outlet tube contacts the canister tube on vehicles built prior to VIN 502997. Install a clip and screw as shown in Figure 3 or wedge foam under the heater tube.

(7) A "clunk" on brake application may be due to rear drums having improper machining. A spiral cut on the drums pulls the shoe outboard on the right side, causing the clunk when it snaps back. The left shoe moves in, and no noise is caused. To correct, turn right brake drum only.

(8) Speedometer noise due to cable being misrouted. Replace cable and case and route properly.

Use applicable labor operation.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
