88 mustang - cleaned the contacts on my door lock switch this weekend, tested them several times they seemed to work fine, locked the car and when I returned the key would not unlock either door. Since my car is a convertble I was able to unlatch the top and reach my hand inside the car and tryed to open doors with door switch and door handle, no luck, removed switches from door still will not open. Both doors stuck in locked position and cannot open either door. Any suggestions?
