So the other night on my way home from work I went to use my cruise control and I discovered that it had stopped working. A few miles down the road I looked down at the dash and my temp guage magically was working (It has not moved above "C" since I have owned the truck)!!! Could the 2 be related??? I did take a look at the fuses and everything looks fine and my horn is working fine. The same symptoms have continued for several days...
