Replacement was very easy
After watching the video to replace my headlight switch for my 2002 GMC Yukon XL, I was very pleased on how easy it was to do the repair. I look forward to repairing other items on my truck and do not missing going to brick and mortar stores where the help can be hit or miss--mostly miss in my area. Thank you for the videos that explain clearly all the steps required and that encourage amateur mechanics like me to complete the job satisfactorily and with confidence.

Geovanny C August 4, 2018
Yes Tom but there are others , what exactly are you looking for ? What vehicle are you working on and what is your problem ? I thought my switch had gone bad ( lost lights ) and as it turns out my turn signal switch had burnt out and I didnt have lights or left turn signal or cruise control , Youre in the right place you just have to narrow the problem down.
