I need help.. I lowered my 2005 Grand Prix today with the 1.8 inch SSC lowering springs. After all was done in over with I got in the car and now have lights and warnings on the DIC and Dash for TCS ABS and variable steering. I put the car back on to the lift and checked for broken wires going into the wheel hub and did not find any.. Any help will be appreciated. Thanks.

Unplug the wires from the hubs clean the contacts on both sides and see what happens.
