Q: How to replace the turn signal flasher and hazard flasher in a Chevrolet C1500 and K1500 equipped with a Delco Loe II anti-theft audio system?
A: On models equipped with a Delco Loe II anti-theft audio system, be sure the The lockout feature is turned off before performing any procedure which requires disconnecting the battery. When the flasher unit is functioning properly, an audible click can be heard during its operation. If the turn signals fail on one side or the other and the flasher unit does not make its characteristic clicking sound, a faulty turn signal bulb is indicated. If both turn signals fail to blink, the problem may be due to a blown Fuse, a faulty flasher unit, a broken switch or a loose or open connection. If a quick check of the fuse box indicates that the turn signal fuse has blown, check the wiring for a short time before installing a new fuse. To replace the flasher, simply pull it out of its electrical connector. Make sure that the replacement-unit is identical to the original. Compare the old one to the new one before installing it. Installation is the reverse of removal. The hazard flasher is checked in a fashion similar to the turn signal flasher. To replace it with another one, simply pull it out from its connector under dash and install a new one instead. Make sure you compare this one with another one before fixing into position in order to ensure you don't fix an inferior unit as you dispose off an authentic brand replacement part which would have taken long trouble and time "to find." Installation is done by reversing what was done when removing it.
