Newbie 2007 Yukon

Here is a pic, second from the right??? I pushed it with the key on and its little light did NOT come on?? I looked in the under hood fuse box and #7, WS washer, has a good fuse in it. Where else should I look to see if my washer fluid heater is working??View attachment 238590

When they disabled the system on my 2007 and gave me my $100, they cut the wire going to the heater and put a heat shrink cap over the wire. Poke around your washer fluid tank and see if there is a stray cable that goes nowhere. The heater was on the tank itself, if I recall correctly and I believe they pulled them because the heater would get too hot and possibly melt the tank.

I have a 2001 gmc yukon slt with a box in the same place and I believe mine is the cruise control module. Could be something different on yours being newer but I'm pretty sure that's what it is.
