I pulled the Heads Up Display unit from my 2000 Grand Prix donor. I have the dimmer switch as well. Tested and worked when pulled. Includes all the wiring connectors and pigtail for custom wiring. $65 ( OBO) shipped to lower 48 states. For shipment outside the area, contact me.
Also, parting out the donor if there is something else that might be of interest ( like the steering column with steering wheel audio controls??)
