MODELS:
2001 - 2002 (JR) Sebring Convertible

SYMPTOM/CONDITION:
The rear window defogger is inoperative and defogger grid terminal(s) is separated from the rear window heating grid and/or may be broken.
DIAGNOSIS:

PARTS REQUIRED:
EQUIPMENT REQUIRED:
NOTE:
DO NOT USE A FLAME TYPE SOLDERING GUN OR SOLDERING GUN RATED GREATER THAN 500 WATTS, DAMAGE TO THE GLASS COULD OCCUR.
REPAIR PROCEDURE:
1. Remove the headliner strap by removing the screw from the carpet, then pull the headliner away from the terminal clip area, (Fig. 1).
2. Remove the wire connector from the terminal clip. If the terminal clip is broken and a portion of the clip is still attached to the heating grid, remove the portion of the clip remaining in the wire connector.
NOTE:
PLACE A PROTECTIVE MAT BELOW THE CLIP AREA TO CATCH ANY SOLDER THAT MAY DRIP OFF OF THE GLASS.
3. If clip has come loose from the glass, skip to step 5.
4. Apply heat with a solder gun to the portion of the terminal clip on the glass until the solder starts to flow, remove the clip then smooth the solder. Wait 5 minutes for the glass to cool before proceeding, (Fig. 2).
5. Clean mating surfaces on grid and new clip with "000" extra fine steel wool.
NOTE:
EXCESSIVE ABRASION MAY WEAR AWAY THE GRID COPPER SURFACE AND GRID CONTINUITY WILL BE LOST.
6. Holding the new terminal clip with a metal "pick" or other suitable pointed tool, place the new terminal clip in the same location as the original terminal clip but with the tip of clip facing outboard.
NOTE:
THE TIP OF THE TERMINAL CLIP MUST FACE OUTBOARD. CLIPS ARE PRE-SOLDERED AND FLUXED. DO NOT REUSE A CLIP IF IT HAS BEEN HEATED PREVIOUSLY.
7. Place the solder gun on the new terminal clip and heat until the solder flows. Remove the solder gun and continue to hold the clip in position for 5 seconds. Let the solder area cool for 10 minutes, (Fig. 3).
8. Attach the wire connector to the terminal clip.
9. Repeat the procedure on the other side of the rear window if the tip of the terminal clip is not facing outboard or the clip has broken or the clip has come loose from the glass.
10. Test the rear window defogger grid for continuity. If successful perform step 11, if not, additional grid diagnosis will be necessary.
11. Install the headliner straps to the carpet using the original screws.
