I would find the circuit breaker relay that supplies power to whichever power distribution box that contains the cooling fan relays. If the box has power, then you may want to consider the following: I feel that if you find out why the fans quit working, then you may also have solved the front turn signal issue.
Electric Fan(s) not working, Checking the fan(s), relay, fuse and engine temperature sensor's.
Verify that the fans work by unplugging them and run jumper wires to the fan(s) from the battery. If they run, your problem lies elsewhere. If either does not run, it's the motor.
Next thing to check is for power at the fan connectors. You have to be cautious doing this because the engine needs to be running and warm if not almost hot, and the A/C also needs to be on. (Both must be on and running for the duration of this checklist.) The A/C fan is on the passenger side and should come on almost the instant the A/C is turned on. It is also the secondary engine cooling fan and should cycle on and off in relation to engine temperature, (If the A/C is OFF). Use a test light to probe the two wires on each fan. If you find power, the fan motor(s) is/are probably bad. If there is no power to fans, roll up your sleeves!
The temperature switch is usually located above the oil filter. If the dash gage is working, its probably OK. Next is the Fan Control Temperature Sensor, located IN or CLOSE to the thermostat housing. You will find out if it is working later is this checklist. I just wanted you to know where it is. Next is the relays and fuse's. Usually located in the engine compartment on the passenger side power distribution box. You will need to remove anything over the cover to open it. If the fuses are OK, tap on the relays or pull them out and push back in. If the fans are still not running, pull a relay and probe the socket terminals for power. Two of the terminals should have power, usually criss-cross from each other. One hot terminal is battery power, and the other is the "signal" voltage which triggers the relay to send 12V battery power to the fan. This signal voltage comes from the sensor at the thermostat. If only one terminal has power, then I would replace the sensor at the thermostat, if not both sensors.

Well I must say you are a master of your craft. Upon receiving your checklist recommendation on the first step I took just happened to notice the three bolt screws on top of engine fuse block. They had loosened from giving jump starts I suppose due to jump post on fuse block. Tightened them and the darn thing works like the first day I had it! Fans blinkers air and nomore over heats.
THANKS A MILLION!
