I have an RS1200EP control module that constantly clicks like a turn signal flasher and will not start the car?????

LED replacement bulbs are nothing but trouble on a vehicle that didn't have them as OEM equipment. In most 'modern' cars, the flashers are controlled by a signal from the Body Control Module or Combined Power Modules via a relay. You need an auto electrician or if the Parts Store sold you the LED bulbs and flasher relay, go back and ask them to sell you the right items to make it flash correctly.

Do you know what a DVOM - digital volt ohmmeter is ? How to use wiring diagrams to test electrical circuits with DVOM? Do you know how the turn signals work ? What controls them ? More then likely it's a problem with turn/hazard flasher module.

Turn Signal/Hazard Lamps
The IGN E 10 A fuse in the underhood fuse block supplies battery positive voltage to the turn signal switch assembly. Ground for the hazard switch is from G302. The FLASHER 15 A fuse in the underhood fuse block supplies battery positive voltage to the turn/hazard flasher module. When the turn signal switch is placed in either the left or right position, a voltage signal is completed from the turn signal switch to the turn/hazard flasher module. When the hazard flasher switch is activated, a ground signal is completed from the hazard switch to the turn/hazard flasher module. The turn/hazard flasher module then sends an on-off voltage signal to the appropriate turn signal lamps, or to all turn signal lamps for hazard operation through these fuses:

Doesn't have a turn signal flasher , use's lighting control module .
Turn Signal and Hazard Lamps The turn signal system consists of:

• turn signal miniature bulbs (13465).
• turn signal indicators in the instrument cluster (10849).
• lighting control module.
• multi-function switch (13K359).
• circuit wiring and circuit protection.

Power is supplied to the lighting control module through instrument panel Fuse 6 (10A). This fuse is hot in START or RUN. The lighting control module is connected to the turn signal switch portion of the multi-function switch. Ground is provided to the lighting control module and the turn signal miniature bulbs through Circuit 57 (BK).
Turn signal functions are performed by double filament bulbs in lamp assemblies located next to the headlamps. The turn/hazard function uses the second filament of the appropriate bulb(s).

• With the multi-function switch in the right turn position, power is supplied to the RH front and rear turn signal miniature bulbs and the right turn indicator in the instrument cluster.
• With the multi-function switch in the left turn position, power is supplied to the LH front and rear turn signal miniature bulbs and the left turn indicator in the instrument cluster.

I would replace the turn signal hazard combo switch.

check all your exterior lightbulbs; the signal circuit is balanced
if a lamp is shorted in the signal circuit the flasher will buzz instead of click

You need to replace the combination flasher module.

Front right and rear right are on a different circuit than the left front an left rear. Locate the Flasher control module behind dash. With key in RUN position check for pulsing battery voltage on the Green/white wire coming out of the flasher control module electrical connector. If no battery voltage, check for battery voltage coming into the flasher from the turn signal switch on the white/red wire. Left turn input is on the white/black wire. If not battery voltage on white/red, but voltage on white/black when turning left, then the turn signal switch is bad

there is a flasher
.the hazard is wired to constant power so it works with the ignition off.
the turn signal works off of a switched power,to the turn switch and either the right or left turn signal.
if a bulb burns out,the light stays on steady

on an older car this woul dsimply mean that the turn signal flasher was burned out for that side. today its more complex. the turn signal flasher is a series of resistors and timer modules located in the workings of the body control module. This can be a simple problem with a shorted line, or a faultly turn switch or something as complex as needing a new body control module. This is something that needs to be repaired by a quality automotive mechnican with an electrical backround, and unfortunatley unless your in the nyc area i have none to suggest to you.

The flasher unit has gone bad and needs to be changed. The flasher module is a part of the hazard module also. The clicking is the unit is still working but there is not enough voltage to activate the lights to flash. It's common on the Malibu's and other GM product cars similar to the Malibu like Grand Am's Ect. I believe Auto Zone has the replacement part for you car and is more reasonable in price then the dealer and the y also have the step by step instructions to replace the flasher module. Good luck and keep me posted, be glad to help.
