How do you turn off the trackion control on a 2008 Uplander

One video and lots of images thinking the Uplander is also in the Impala. Perhaps it is.

That's where the ABS pump is, so yes. Get the trouble codes read before you replace anything

battery secure? make sure battery isn't moving around

The only info I found was, control arm nuts--162 ft lbs
Hope we are talking about the same thing?

Does the switch works in other modes ( ac, def ) If not , ck power & ground at the fan itself in all modes., If OK R/R the fan. If the fan only loses power or ground in heater mode look toward the wiring------switch control. Good Luck.

THE I/P FUSE PANEL THE FUSE IS THE STOP/TURN FUSE 12
20 AMPS

DID YOU CHECK FUSES? DID IT START ALL OF A SUDDEN? IS IT ON BOTH SIDES?

Doesn't have a flasher , the BCM - body control module turns the turn signals on an off .
Turn Signal Lamps
The STOP/TURN fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to the body control module (BCM) for the turn signal lamps. When the turn switch is placed in the left or right position, ground is applied to the BCM on the left or right turn signal switch signal circuit. The BCM then applies voltage to the appropriate front and rear supply voltage circuits.
Grounds for the various lamps are as follows:
• G100 supplies the right front lamps
• G101 supplies the left front lamps
• G400 supplies the right rear lamps
• G401 supplies the left rear lamps

• An internal fault within the yaw rate sensor/lateral accelerometer, P/N 15189628, may be the first possible cause. • The vehicle stability enhancement system (VSES) electronic brake traction control module See if this info helps
