Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Has anything been checked,tested or replaced to try and locate or repair this issue here at all?
Let me know so we can continue from here,thanks Pete.
O.k.,the first thing to check is to make sure the low beam bulbs are all o.k. and do not need replaced.In some cases they can burn out and need replaced.If these are o.k. if your high beams do work but not the low beams the most common cause is the dimmer switch itself/multifunction switch that switches between low and high beam.To find out for sure if this switch is the cause needing replaced this will need tested with a multi meter or test light.If you have this tool to test this let me know and I can walk you through this testing.
The other component that will cause this is an internal electrical fault in the BCM (body control module) but usually this is just an issue with either burned out bulbs or the multi function switch itself needing replaced.

The cost of the turn signal switch can run around $200 in some cases and is the switch located behind the steering wheel that the turn signal lever is attached to.Labor to replace it is an hours charge so you may be looking at $300 parts and labor to have replaced.You want to locate the dark bluw wire coming out of the switch at terminal C and this should have a ground signal on this circuit with the low beams switched on.If you have no ground signal at this switch then the switch needs replaced.
