After installing hitch wiring my cruise control can be disabled by activating the turn signal. This did not happen right away, but soon after. It was also wet the day I drove the car for the first time with the hitch on pulling a small trailer.

On a side note, i hit a bump and all the dash lights turned off for a second or two and then came back on.

So, any ideas why the blinker would deactivate the cruise?

 

check the fuse(s)

 

Ok...good idea, thanks!

 

I am not familiar with the installation of the hitch kit, but I would double check any wiring you did as well for pinch points. Specifically there may be a place where the wires are pinched and are getting rubbed bare allowing them to short. Do all the lights on the trailer work correctly?

 

If you hit a bump and all the lights turned off, check the battery terminals.

 

Thanks guys...I'll look into it some time this winter when i decide to deal with the cold garage.
