Hey everyone. I have an 02 hd150 with 105000. My cruise control works great, most of the time. Heres the deal. if its cold outside it works for quite awhile. if its hot out, it may work for 15-20 miles. it turns itself off. then you may not be able to turn it back on. maybe you can, maybe you can. kinda frustrating. is there a relay or somethin that maybe be wearin out? maybe the cruise module itself? have had the trans checked and all is good there. hopeing someone on here can point me in right direction. thanks in advance.
