In place of the sensor

 

did u ever get the flickering fixed?

if not im 95% sure ur ballast is going bad. happened to me i just replaced the ballast and good as new... mine happened because the stupid double sided tape that everyone uses didnt work and it was bumping everywhere. so i got new DIGITAL BALLAST with brackets.

 

Take the pillars off, pop the dash cover off that has the sensor in it. Unplug the sensor, install the resistor in the plug and tap it up tight or you can fight to solder it in the wires. Mine has been like this for 3 yrs no issue also pull your drl fuses

Awesome, thanks! One of the work Tahoes I drove was modified so you had to rotate the **** all the way to the right to turn kn the headlights, but I wasn't sure how to do it. What impact does this have on the brightness of the instrument backlighting and the radio?

 

Gauge cluster is normal, radio is Always bright

 

Hmmm. Thanks for the heads-up; I'll see what I come up with.

 

IF you are going to do the 6 hi mod dont do the resistor. Use a relay I did it this way and its much more safe and cleaner
