Hi all,
Well I found a used relay control on ebay for a 2004...changed out the bracket with my old one and bingo...bango...
everything the way it used to be before winter. Total cost 247.00 and my time of course...
Now I am looking for info on speedometer not functioning...pulled out onto the highway... the needle bounced a couple of times
and stopped working. Any ideas...??? Does it use a speedometer cable or is it electronic??? Any help appreciated...
