When I use turn signal to turn left it only works occasionally. No problem with right signal, or cruise, or wipers. Do you think the signal switch needs replaced and can you tell me what is involved to do so.
Thank you,

Make sure your bulbs are ok first and the grounds are good. It's quite involved.
Disable the SIR system. Refer to SIR Disabling and Enabling Zone 3 in SIR.
Remove the upper and lower trim covers. Refer to Steering Column Trim Covers Replacement.
IMPORTANT:The abrasion sleeve located on the steering column wire harness assembly must be reinstalled. Make note of what connector is coming out of the abrasion sleeve for installation purposes.

Remove the wire harness assembly (1) from the wire harness strap (2).
Disconnect the turn signal and multifunction switch assembly connector from the SIR system coil connector.
