[QUOTE="SNAKEYE, post: 3870167, member: 22534"] Not to dismiss the success of those who had their multi-function switch replaced and got their turnsignals back to a proper flashing rate BUT the multi-function switch has nothing to do with effecting the rate of turnsignal/hazard warning flashes as it simply directs the power to the bulbs to be flashed. For that matter, whether all bulbs in the turnsignal/hazard warning circuits are good or not, the rate of the flashing is not effected. Why you ask?: because the flasher units in our Cobras are electronic. They are not the old bi-metallic strip-type flasher units (the little aluminum can looking thing) with the bi-metallic strip that heats-bends-clicks-cools-bends back-repeats same, of yesteryear. They are solid-state with circuitry that is uneffected by the number of bulbs being operated (4 in turnsignal mode, 8 in hazard warning mode). Two things (other than manual internal modification, ie. sequential turnsignals) could effect the rate: 1) something is wrong with the power supply/ground circuits to the flasher unit, or 2) the flasher unit has had an internal component failure of some type. No. 1 can be caused by poor contact of the flasher unit's prongs in the plug. Find the flasher unit ( mine is a yellow plastic thingy about 1" square by 1-1/2" long) up under the dash by the fuse block, unplug it from its connector and plug it back in. Check for flasher rate. If OK you're done. If not, the grounding side of the flasher unit's supply circuit may have a bad ground connection effecting overall supply voltage to the flasher unit. The ground connection for the flasher unit is located on the right side of the console up under the dash. There are two green screws there with three wires grounded to the metal frame of the dash-to-console steel frame. No need to determine which screw specifically grounds the flasher unit, just unscrew both of them. Clean (emery or sand paper) the rusty steel frame surface where the wire terminal lugs contact the steel. Clean the lugs themselves. Wipe any residue off of the steel surface. Solder the exposed bare ends of the wires in the lugs to the lugs (this will assure proper electrical connection of the wire to the lug and eliminate any possible problem within the lug's compression barrel).
