2008 Winnebago Journey 39z input

My first Journey had manual locks. The one I have now (a 2007 purchased used in 2016) has the electric slide locks on the two front slides. I had never had electric locks before, but followed the procedure for their use, but I was never hearing anything and wondered if they were working. I contacted Winnebago and was told there is an audible "click" when they lock, so was advised they are probably not working. Haven't done anything about it yet, but have never noticed any movement of the slides while traveling. I will probably get around to checking them out this year.
