Thanks John, I was thinking that perhaps one was rear defroft, but will have to check all of my fuses to know for sure, also it should snow here again, so can really tell. Also I will turn on the" no graphic swicth to see if rear light comes on. Jerry

Question #2. On the dashboard- lefthand side-behind steering wheel is a black lever. when it is turned all the way to the right the engine idles slow and rough, when it is all the way to the left the engine idles higher and runs smoother, also at this setting the rpms take longer to return to normal. What is the function of this lever?
