Grand Prix V6-3100 3.1L MFI VIN M (1994)
The wires on the windshield washer/wiper switch assembly may have been routed incorrectly when installed (see Figure 1). This restricts the movement
of the switch, preventing it from staying in position.
Cause # 2
The old design windshield washer/wiper switch has wires that are thicker than the cruise control wires. During cold weather, the thicker wires may be
rigid enough to prevent the turn signal from holding its position. Harnesses identified with "9554 - REV 1" on the tag (see Figure 3) use thinner wires.
This change was in production after approximately Sept. 1, 1994.
Correction
1.
Disconnect the negative battery cable. Disable the SIR system, following Service Manual instructions in Section 3F5.
Caution:
The Service Manual procedures must be followed in the order listed to temporarily disable the Supplemental Inflatable Restraint (SIR) system
and prevent false diagnostic codes from setting. Failure to follow the procedures could result in possible airbag deployment, personal Injury, or
otherwise unneeded SIR system repairs.
2.
Remove the lower left trim panel to expose the lower steering column wire harness (see Figure 3). If the label has "9554 - REV 1", the wires are
thinner, and the switch assembly will not have to be replaced. Continue to Step 3.
If the label shows "REV.009" or lower, or "0898", replace the switch assembly with P/N 26049554. See Step 3 below to insure that the wires on
the switch are routed correctly.
3.
Disassemble the upper steering column components, following Service Manual instructions, to expose the switch assembly. See Figures 1 and 2.
Make sure that the wires are routed as shown in Figure 2, NOT as in Figure 1.
