I was wondering if there are any relays for the indicaters or how i can find a wiring diagram for a jeep grand cherokee. none of my blinkers are working but my hazards still work.Also I was wondering where the flasher bulb on it would be interior.

Your problem is not a fuse if just the right front isn't working , same for all indicators .
Turn Signal Lamps
The TURN fuse in the fuse block - I/P provides ignition positive voltage to the turn signal relay. The turn signal lamps may only be activated with the ignition switch in the ON position. When the turn signal switch is placed in either the left or right position, current flow is from the turn signal relay output to the turn signal switch assembly. The turn signal relay sends an ON-OFF voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator through the turn signal switch.
an it's not a bad relay , if there is no B+ voltage at the lamp you have an open circuit . You would need a wiring diagram to test circuit from turn lamp back to source voltage to find open . free wiring diagrams at www.bbbind.com . video on youtube testing voltage drop Mastering Voltage Drop Testing with Pete Meier and Jerry Truglia
There could be no relay in the vehicle because it doesn't need one. CANbus vehicles tend to use a single module to carry out all the vehicle timing requirements - indicators, hazards, wipers, courtesy lights and so forth.
If the flashers don't work it would be better to repair the system than to rewire and use an outdated method, perhaps introducing further fault codes that might affect the operation of other stuff.
A little used hazard switch is a common cause of flasher failure...
If you really must rewire the system, the (ignition) live, as you say, goes to one side of the flasher unit and the other to the centre contact of the indicator switch though you will need a wiring diagram to identify the colour. There is no single universal colour code though if I was looking at an old British car I would expect to see a dark green wire with a thin black trace line.
A wiring diagram will be useful also for identifying the wiring to the lamps and separating the hazard switch wiring from the circuit. If there are two dashboard tell-tale lights the 2-pin relay will be ok but if there is only one you will need a 3 or 4 pin unit depending on whether electronic or electro-mechanical.
I think the purple wire (or maybe the yellow) from the neutral safety switch goes to the coil side of the starter relay, turning it on so power is sent from there to the starter solenoid. You could check for this signal to the relay with a test light. The key must be held in start while you probe the other two terminals for the relay. If the signal is there, either a bad relay or the coil side of relay is not grounded properly. It is possible that the coil side ground is the neutral safety switch-grounding the relay's coil side only in park or neutral-in which case the nagging light on shifter (between off and run, it only works?) may be telling you the safety switch is the problem.
You may need to look at a wiring diagram, Greg. But the starter relay is the last component in the start circuit before the starter solenoid. From battery to ignition switch to "crank" fuse to neutral safety switch to starter relay to starter solenoid to starter-and back to battery through ground. That is the start circuit. Just that the wiring tying them all together makes it complicated.
Can't supply a diagram but I can tell you that 15A fuse 27 in the central junction box (CJB) applies power via a LT BLU/PNK wire to terminal 2 (the coil) of the indicator flasher relay in auxiliary relay box 1. 20A fuse 18 in the CJB applies power via a LTGRN/RED wire to the brake pedal position switch and terminal 3 (the relay arm). Terminal 5 of the relay connects the relay coil to ground (BLK wire). Terminal 1 of the relay supplies power via the LT BLU wire to the turn signals when the relay is closed. Terminal 4 supplies power via the WHT/RED wire to the hazard light circuit when the relay is open.
3 things to check here assuming the fans are good. Fuses and relays, wiring and connections or fan temp sending unit. Dont think because the sender for the guage working indicates that the fans should work. Most cars have a seperate sensor for the fans. I dont have a wiring diagram so I cant tell you where the relays, sensors or fuses are on this model but this should at least get you started in the right direction.
Hope this helps... Dale
