help..electrical gremilns
 

hi..need help
Boxster 2003 manual
electrical issue started yesterday.
Interior lights stayed on, central locking will not work.Horn sounds when the locking button on remote is pushed, car will not lock.Will only lock with the key.
Driver side window wont go all the way up, about 10mm below seal on the roof.
Small , but frustrating issues that i cant seem to solve.

Any help is appreciated.

I'd check the battery (load test), and the alternator output (~14 V); if they are fine I'd look at the switch section of the ignition switch.............

Check for ...
 

... dampness under the driver's seat.
It sounds like a wet CLU (Central Locking Unit) issue.
If you find dampness:
• Disconnect the battery
• Remove the driver's seat
• Disconnect the CLU and remove from floorboard
• Open the case and remove the printed circuit board
• Place the PCB in a shallow dish and cover with Isopropyl Alcohol (rubbing alcohol)
• Shake it and give it about 10 min immersed
• Let the PCB drip-dry and then air-dry (don't use forced drying such as heat)
• Once completely dry, reassemble everything.

Happy Boxstering,
Pedro
