ok guys been working off and on of this eldog for 6 or so months. the cruise control works sometimes then others it doesnt work. when its working. no problems it will work sometimes then when you press the resume button after cruise has been cut off with the brake pedal it will no reacitve until you touch the gas. when it activates it goes to appx 75% throttle to get back up to speed. also the dash lights where if will show fuel millage and heat and air temp work sometimes then they dont others. heres the kicker guys. when the dash lights work the gas guage doesnt, when they are working the gas guage goes to full no mater what the tank level acutally is. also sometimes the keyless entry works when it wants to also.
