54 A S P D e c e m b e r 2 018 T e c h n i c a l S e r v i c e B u l l e t i n s CADILLAC CADDY COLUMN CORRECTION Owners of a 2011 Cadillac SRX may complain about a tilt/telescopic steering col- umn lever that is binding, sticking or difficult to lock. is may be caused by the steer- ing wheel lever adjustment nut tightening over time when the lever is cycled. Use the following steps to in- stall a thrust washer under the steering wheel lever adjustment nut. is will prevent unwanted tightening of the adjustment nut when the lever is cycled: Remove the steering column trim covers. If the steering column has a sound deadener, remove the star washer that retains the deadening material to the col- umn. Reposition the sound deadener to allow access to the repair area. NOTE: e removal and re-install of the adjustment nut must be done with the tilt lever in the locked position. During the following steps, the tilt lever must be held in posi- tion toward the center of the column to maintain pressure on the needle mechanism until the adjustment nut is re-installed. With the tilt lever in the locked position, remove the nut. Install the thrust washer on the clamping bolt against the flat washer. Re-install the nut until it bottoms out on the new thrust washer. The lock /unlock tilt lever effort should be very low, but should retain at the detent point. Increase torque on the nut by small increments and check the steering wheel adjustment lever effort (lock/unlock). Con- tinue to increase the torque un- til the load on the steering wheel adjustment lever has the correct effort. Cycle the lever several times to ensure that there is no in- crease on the lever effort. Re-position the sound dead- ening and re-install the star washer. Re-install the column trim covers. Obtain and install a new thrust washer, P/N 22864581. Keep the lever in the locked position, pushed toward the center of the column until the adjuster nut is re-installed. Remove the column trim covers and sound deadener. With the thrust washer in place, incrementally torque the adjuster nut until the proper lever effort is obtained. JEEP COMMANDING THE JEEP This bulletin applies to 2010 Jeep Command- er vehicles, where the customer experiences a rear defroster switch that has higher than desired engagement effort (too hard to en- gage). is condition is caused by the ATC hous- ing having too much deflection when the button is depressed, which does not close the switch properly, requiring extra effort to close the switch. Remove the ATC control head. Follow the pro- cedures available in DealerCONNECT/TechCONNECT. Refer to Group 24 – Heating & Air Condition- ing > Controls > Controls, A/C and Heater Removal procedures. Install two new screws into the back of the ATC control head. e screws are available as P/N 68078941AA. Install the ATC control head.
