Had a new stereo head unit installed by 'qualified' car stereo installer. Tow/haul became stuck on after installation and installer could not find any flaw. Paid Livermore Ford $200 and they identified the flaw, in spite of informing them that it showed up after new head unit, as a failed gear shift button and offered to 'fix' the problem for ONLY $600. After detailed investigation with an ohm meter, I discovered the failure to be the integration of the tow/haul wire incorrectly during the stereo head unit installation. If Livermore Ford were a reputable outfit they would return my $200 fee for troubleshooting at which they failed utterly. They apparently have become so dependent on computer investigation that all sense of hearing the customer has been eradicated from their culture. They receive a zero for this assignment. Moreover, they took my email and, after stating plainly that I do NOT want email, sent email advertising. I am angry over this failure of respect for the custormer, read review accordingly.
