Mustang Modified Flasher Install

Sounds more like the flasher to me,in the drivers side fuse panel
square box ,looks like a relay , 5 male spade connectors on back.

turn signal switch on column needs to be looked at.

the clpicking is the compressor for the a/c. If you turn your steering wheel left or right does the key come out? When did you have a tune up?

loosen the inner fender and you can access it from behind

check the fuse box check the running lights also one bad bulb could cause it to go all wacky.

could be a bad connection on the plug or a broken wire it could have corrosion on the connector

the rapid blink is because there is a bulb outage some where, Pull Over turn on left Blinker Get out of your car look at the front left blinker hen walk to the rear of your car and look at the left rear Blinker light then do the same for the right side blinkers if all are working rapidly your left right switch is bad

Pull that bulb out and look closely at it, it'll probably have one of the filaments(Tungsten wires) broken and crossed over to the other one causing a short to power and/or the bottom of the bulb has had the 2 lead contacts melt together. In either case the bulb will need to be replaced. If this doesn't fix the problem please let me know so I can look into it further.

If ALL Wiring in Trunk is Good Then Its The SWITCH = Multifunction Switch<<
