Review on 💡 Enhanced Control with Standard Motor Products DWS394: Driver-Side Power Window Switch with Power Folding Side-Mirrors and Adjustable Pedals. by Hartman Hernandez

It did not work properly because when the unit was received the instructions in the box said "This switch is designed to work with 'ELECTRICAL FOLDING MIRROR'". "NO PROGRAMMING REQUIRED". "Witch" is used when towing/pulling a trailer. When I installed it, only the driver's window worked. When the window was raised again, the door locks were activated at the same time. Good product just not for my 2003 model. GMC Yukon, which is clearly stated. This matches your 2003 GMC on the Amazon website. BTW, I don't tow or tow anything with my Yukon.
