Hey guys I have a 88 mustang convertible gt, all stock and I’ve got this problem that some times I start the car and the check oil light is on the convertible top won’t work and the turn signals won’t work. If I turn it off and back on it sometimes works. What can I look for or try?

Revised 7-June-2014 to add Torx bit picture and source. Also added replacement ignition switch wiring pigtail picture, part numbers and sources.
Some of the symptoms of ignition switch problems are things that don’t work or are intermittent like radio, turn signals, wipers or heater.
There was a FREE recall on Ford ignition switches. They overheat and sometimes catch fire. That burns up the steering column and sometimes the car interior. Since this is very old information, you may not be able to get the switch replaced for free anymore. The auto parts stores sell the switches for $13-$15.
While you are working on the switch, check the wiring and connector closely. A replacement connector with new wiring pigtails is available from most auto parts stores
AutoZone and Advanced Auto Parts have the same Part Number: 434 - may have to order, not always in stock
Autocraft torx bit set – have small hole in tip for tamper proof screws.
Part No. AC571/W1386 Cost approx. $12 +tax
