Not sure what brand of WDH you own, or even if you have one. We need to know some details about your towing setup in order to provide any info/assistance.
Chances are, if you have a quality WDH, it is not setup correctly. If your using the setup made by the dealer, chances are even higher that it is not setup correctly. Most of us have had to reset up/adjust our WDH to operate properly. Give some info here and I'm sure this forum can help you!
