How do I get the plastic cover off to replace the turn signal switch. I could get the bottom loose but couldn't get the top loose or any of it removed.
Do I need to remove steering wheel? I hope not!
Please give me a step by step to replace this switch.
Thanks and God Bless, Ken Wilson 330-209-3061
