more grand prix problems

[fishingstar]

My sons grand prix has a problem shifting out of park. I was thinking it was the park solenoid. Now sometimes it works It is about a 50/50 mix. Just wondering if this is common.

Thanks

Could it be an ignition or brake interlock? Is there an over-ride release button? If so, does this work?

Unfortunately it is fairly common. It is likely the shift interlock that is the problem and it activates when pressing the brake pedal, but when the solenoid goes bad it won't release. There is an override that you can push to release it, but depending on the year of the vehicle it's in different locations.

This car has electrical problems with the battery going dead after sitting for more then 4 or 5 days. I think that's in the ignition switch. The light on the dash for the security system stays on.

I don't if this is the same problem or not but he has been using the manual release.

Also make sure the brake lights are coming on when the brake pedal is depressed and the interlock is NOT working. If there are no brake lights than the solenoid is not getting power as well to release the shift lever from park.

I would be concerned about the security light being on solid. Usually, depending on the problem, there is a fault with the security system and it could be in a "limp" mode. Disconnecting the battery completely may shut down the vehicle until the security system is repaired.

the brake lights worked today like the shiftier. The security light is not solid it flashes.

He unhooks the battery when he gets back to school.
