Rear Compartment (Trunk) Lid Latch Difficult to Unlock/Open
(Inspect/Replace Cable and Secure with Strap)
1995-99 Chevrolet Cavalier
1995-99 Pontiac Sunfire
without RPO AUO (Remote Keyless Entry System)
Some customers may comment that the rear compartment (trunk) lid is difficult to unlock with the key.
The tab on the cable assembly that secures it to the latch assembly may have broken. When this occurs, the cable may disengage from the latch.
Using the following procedure, inspect the tab on the cable assembly for signs of breakage. Replace the cable assembly if the tab is broken. If the tab is not broken, reinstall the cable to the latch. Secure the cable to the latch assembly with plastic strap.
1. Open the rear compartment lid to access the latch on the inside.
2. Remove the fastener securing the cable to the latch (see Figure 1).
3. Inspect the tab on the backside of the cable for signs of breakage (see Figure 2).
If the tab has NOT disengaged from the latch after removing the fastener, the tab is in acceptable condition and it is NOT necessary to replace the cable assembly. Reinstall the fastener that secures the cable assembly to the latch.
If the tab HAS disengaged from the latch after removing the fastener, the tab is broken and the cable assembly must be replaced with a new cable, P/N 22606550. See the appropriate Service Manual for information on replacing the cable assembly.
4. Using one (1) plastic strap, P/N 12355066, secure the cable portion of the assembly to the latch as shown in Figure 1.
5. Trim off excess strap material.
Parts are currently available from GMSPO.
