When trying to put my top down I have a message that it has a TLAT switch failure. I took it to the dealership and they told me that two switches were open and the cost to fix the problem would cost $2700.00.. Does anyone have a source for these switches. The dealer said I can't buy just the switch bit needed to buy the whole unit for a cost of $2000.00 for the parts. Needless to say I declined and am looking to see if just the switches can be purchased.
