Discovered the same problem in my Prix yesterday, something is affecting the lights sensor cause you can still turn them on manually, I'm going to check the DRL sensor wiring for shorts or something, will post again if I figure it out.
you either have a bad door switch, any of them could be bad. or you have the lights physically turned on at the switch.
how do you replace backup lights on 99 grand am?

The blower motor is located under the dashboard behind the glove box. Remove the glove box, passenger side scat and the blower motor will be visable.
it is on the firewall and difficult but not impossible to get to and replace.
On a 1999 Jeep Grand Cherokee, the blower fuse is located in the fuse box, which is typically found under the dashboard on the driver's side. You can identify the specific fuse for the blower motor by consulting the fuse diagram on the cover of the fuse box. It is usually labeled as "Blower" or "Heater." Be sure to check the fuse for any signs of damage and replace it if necessary.

Blower fan relay is stuck or fused contacts, replace it
i broke down and paid to have this fixed. My mechanic said this is a fairly common problem on the older grand prixs. He had to replace the relay as well as the blower motor, total cost was $400.
To fix or disconnect the daytime running lights on a 1999 Grand Prix, you could begin by checking the running light fuse. If the fuse is damaged or blown, you can replace it to fix the lights. Remove the fuse if you want to disable to the lights.
I don't know, but go ask a mechanic
