Today I started my 99 SL500 and backed it out of the garage and after parking it I noticed the power antenna remained extended. I tried starting the car and turning the radio off and on but still with the same problem. After that I tried to open the truck and it did not open. I tried unlocking with the remote and noted the parking lights flashing but I could not hear the solenoid in the trunk working, so I manually unlocked the truck to check the fuses, all of which seemed to be ok. After this I also noticed that when I tried to lock or unlock the car using the remote that the parking lights flash but the door locks do not respond at all. The car has been sitting for awhile, I do start it at least once every 3 weeks but have never had any problems with it before. Any help appreciated.....I searched the posts but was unable to come up with anything. Also the owners manual is locked in the compartment behind the passengers seat, which seems to be locked.....ugggh summer is almost here and my SL is suddenly plauged with these electrical gremlins.
