WATER LEAK AT SUNROOF OPENING (INFINITY AMPLIFIER WET)
DESCRIPTION:
Some 2003 Tiburon vehicles may develop a water leak from the rear of the sunroof opening. If a water leak occurs, it can leak into the Infinity amplifier, causing static or no sound from the audio system. Other symptoms include wetness on the "C" pillar trim near the seat belt holder, or a damp rear seat.
NOTE:
Before diagnosing a vehicle with no sound from the radio, first check to see if it is equipped with the Infinity sound system. If it has the Infinity (JBL) amplifier, it must also have the Infinity version of the H280 head unit (H280-JBL). The H280-JBL head unit has "Infinity" printed on the front. The standard H280 does not. The standard H280 will not turn on the amplifier.
SERVICE PROCEDURE:
1. Tilt the sunroof up, but do not slide it back. Keep the sunshade as closed as possible.
2. Reach under the roof panel lip behind the sunroof with one hand.
3. Apply shop air to the body seams with the other hand.
CAUTION:
Wear safety glasses.
NOTE:
The sunroof glass can be removed for easier access.
4. If air leaks can be felt under the roof, look for skips in the seam sealer.
5. Apply a flat bead of clear silicone sealer over the unsealed seams. Be sure to fill the rear seams as necessary to seal them.
CAUTION:
Apply a flat bead of sealant to allow the sunroof gasket to seal. Fill the rear seams flush with the sheet metal edge, not overflush.
CAUTION:
Do not close the sunroof until the sealant has completely dried.
6. Retest the area for air leaks.
Other possible causes of leaks from the sunroof area are:
^ Disconnected sunroof drain hoses
^ Damaged sunroof frame seal tape
^ Damaged sunroof glass gasket
^ Severely misaligned sunroof glass with a large gap on one side.
If the Infinity amplifier may have experienced damage related to a water leak, the amplifier must be removed, dried if necessary, and inspected for proper operation. The connectors should be flushed with contact cleaner, and filled with connector grease for protection.
WARRANTY INFORMATION:
Normal warranty coverage applies. Use the proper labor operation as per the LTS manual.
