Tip inhibitor switch replacement DIY?

[mikesz]

I have a 99 Tip. The shifter buttons on the steering wheel do not work and never did(I am third owner). I am told its probably the inhibitor switch. Has anyone replaced this? I am currently replacing the right inner cv joint and rebuilding suspension so I figured now might be a good time to replace that switch. I have one just looking for a DIY.

Exactly the same as the last time you asked in 2015:

 

The following procedure is for Boxster only.

Removing and installing multi-function switch

 

Removal

1. Hold engine by transport shackle in installed position with special tools 10 -222A and 9591/1

 

 

2. Remove the left catalytic converter.

3. Detach selector lever cable from deflection lever and transmission support.

 

 

4. Place transmission jack under the transmission.

5. Remove the left transmission support with hydraulic mount.

 

Note:

The fastening nut M12 © must not be loosened. The transmission support will otherwise be damaged.

 

 

A -Transmission support

B -Hydraulic mount

C -fastening nut M12

6. Release and disconnect cable connection to multi-function switch.

 

7. Unscrew fastening screws and pull switch off the selector shaft.

 

 

 

Installation

Install in the reverse order.

 

Put multi-function switch on the selector shaft. The flat point on the serrations in the switch (3) must lie against the flat point on the selector shaft (1).

 

 

Note:

Place multi-function switch on the selector shaft. Do not tilt or use force: you may damage the switch contacts.

2. Turn switch until the fitting bore (4) can be put on the dowel pin (2) on the transmission housing.

 

 

Tightening torques

Multi-functions witch to transmission housing -- (M6) = 8 Nm (6 ftlb.)

Transmission prop to transmission housing -- (MID) = 65 Nm (48 ftlb.)

Hydraulic mount to carrier side section -- (M8) = 23 Nm (17 ftlb.)
