Gmc Sticky Locks
2007-2013 GMC Denali, Sierra or Yukon vehicles may exhibit a condition where one or more of the doors does not lock/unlock when activating the power door locks. The condition may be intermittent or constant. The cause may be that the door locking button is hanging up on the window belt inner sealing strip within the door. The inboard seal material may rub on the button.
It is not necessary to remove the door trim panel. Verify the condition by removing the door locking rod knob. Ensure that the locking rod is in the unlocked position.
Use a flat-bladed tool to disengage the detent tab and then remove the knob by pulling up. Verify interference of the door lock button to the sealing strip by visually inspecting the area behind the button for sealing strip material protruding into the door lock button area. Use a trim stick or suitable tool to reposition the sealing strip to the outboard side of the down-standing tab. When reinstalling the lock knob, push the knob down until the detent tab touches the locking rod opening cover. Push the detent tab in to lock the knob to the locking rod.
Mazda Keep Brake Sensors Clean
Is the SCBS (smart city brake support) warning light on in a 2016-1028 Mazda2, 2014-2018 Mazda3, 2014-2017 Mazda6, 2016-2018 CX-3, 2014-2018 CX-5 or 20162017 CX-9 vehicle? Chances are the exterior sensors are simply dirty. Clean the windshield and front grille emblem. The light may also be on in rainy conditions if the windshield is fogged or if it is raining. Operate the wipers and turn on the defroster.
equipped with an 8.4-inch touchscreen display. The front defrost button may not respond at times. The touch screen’s climate controls may ignore the rst press of the defrost button if it is the rst climate button pressed after ignition on. The second press of the button may work correctly. If another climate button is pressed prior to the front defrost button, the control may respond as desired.
Selectively erasing and reprogramming the HVAC control module with new software is required. The wiTECH software level must be at release 14.02 or higher. Perform the Actuator Calibration Test routine found under the System Test tab in the HVAC control module view in the wiTECH Diagnostic Application. After HVAC programming is complete, clear any DTCs.

This bulletin applies to 2014 RAM 1500, 2500, 3500 and 4500/5500 trucks
Subaru Fob Is Out Of Date
There have been isolated reports of inoperative remote engine start (RES) fobs on 2017 and later Subaru Impreza vehicles, where the blue LED does not illuminate when pressing the start button. The cause of this is a dead battery in the fob itself, due to a software error. The a ected RES kits are H001SFL000-2017, Impreza with push-start ignition, and H001SFL100-2017, with turn-key start ignition.
The repair for this condition is to order a replacement fob, P/N H001SFL020, which has the updated software. 05149062AA. Clear the DTC.
Ford Mustang Clutch Switch
Some 2015-2017 Ford Mustang vehicles equipped with a manual transmission and built on or before June 15, 2016, may exhibit a no-crank condition due to the CPP (clutch pedal position) switch being damaged.
Cadillac Detecting A Rattle
Some owners of 2014-2016 Cadillac CTS or XTS vehicles equipped with a 3.6L turbocharged engine may comment about a brief rattle or tick when revving the engine when the transmission is in Park or Neutral. The same rattle can sometimes be heard at the beginning or end of acceleration while in Drive. This condition may be caused by loose converter bracket nuts or it may be a normal characteristic of the turbo wastegate.
Inspect the M8 nuts that secure the catalytic converter to the exhaust bracket. If the nuts are loose, it is necessary to replace them with new torque prevailing nuts P/N 11546441. If the nuts are found to be torqued correctly, do not replace the turbo assembly in an e ort to eliminate this brief rattle.
If the CPP switch is damaged, install a new CPP switch and bracket, P/N HR3Z-11A152-A. The new switch includes a plastic bracket rotating the connector 90-degrees.
Chevy Corvette Torque Tube Tips
This bulletin applies to 2014-2018 Chevy Corvette vehicles. Whenever the driveline support (torque tube) is removed for any reason, special care must be taken to make sure that the propeller shaft splines are in alignment with the front hub bearing. The torque tube must be aligned with the engine bellhousing before attempting to tighten the attachment bolts.
The propeller input shaft front bearing positioning system is designed to withstand an insertion force not greater than 130 pounds of force. Using the fastening bolts as an installation method may create force above this amount, causing damage to the crankshaft thrust bearing.
Bmw Wiper Surprise
2015-2019 BMW 2 Series, 3 Series and 4 Series vehicles may present a condition where the windshield wipers may switch on by themselves and can no longer be switched o despite activation of the switch. The cause is an internal software error in the SZL (steering column switch cluster). The correction involves replacement of the SZL. The SZL does not require programming/coding after replacement.
When reinstalling the torque tube, the angle may be slightly o horizontally or vertically, which can make alignment di cult. Do not use the bellhousing bolts to draw the torque tube tight against the bellhousing. Any small amount of misalignment may cause the input splines to catch on the crankshaft, driving it forward. If the engine is started with this condition, it may cause the crank thrust bearing to be immediately worn, necessitating engine rebuild or replacement.
