  Q: How to replace the Neutral Safety Switch on Buick Rendezvous?

  A: Before you begin replacement of the pnp switch you should first engage the park brake and wheel blocking followed by switching the transmission to neutral position. First disconnect the throttle body air inlet duct then use a flat-bladed tool to free the automatic transaxle range selector cable from its lever connection. Unplug all electrical connectors before taking out the automatic transaxle range selector lever and pnp switch bolts then finally removing the pnp switch itself. Before fitting the new pnp switch you must place the transaxle in neutral since the switch arrives in the neutral configuration. Check the transmission position for neutral when the bolt holes fail to match. Line up the flat surfaces of the shift shaft with the pnp switch's flats before putting the switch on the transaxle then bolt the switch in place with j 41545 bolts tightened to 25 nm (18 ft. Lbs.). After installing the automatic transaxle range selector lever and electrical connectors put the automatic transaxle range selector cable into position. Testing should take place after confirming the engine only operates when the shift selector is in park or neutral position and then reinstall the throttle body air inlet duct while removing wheel blocks and releasing the park brake.
