OK well i finished my heatercore install...everything works good...but i have three problems..the horn, cigeratte lighter, and the speed control don't work...i looked up the horn on my ford cd shop manual, and it shows that the horn and cigeratte ligther are together, so i must be missing something for those things not to work? you guys have any ideas of what i could have missed or what to check for? I plan on looking tomorrow, but i thought maybe you guys could give me an idea of what i could have possibly missed, thanks
