Hello and thank you for this forum. I’m having trouble with the retractible hard top. It won’t go down. The four windows go down and then nothing. Also the fob key won’t open the doors. It starts car. Dealership said it’s something within the car and not fob. I have appointment for further diagnostics this week but wondering if I can fix it myself. Where do I start with trouble shooting? Thank you in advance for the guidance.
