you need to take glove box out. It's right behind three three 7mm bolts for the plastic piece that holds it in. two 10 mm nuts that hold it to the plastic piece. Should come right out with a little finessed force.

The flsher shoul be plugged into the fuse panel. Turn on and listen. If turn signal is not working, The bulb is more likely the problem. Good luck.

Are you sure that you don't mean the cooling fan control module? It should be located up front next to the cooling fan. It is square shaped and has a long square shaped plug going into it. Reads the temperature of the coolant and passes the information to the engine control computer (ECC). The ECC receives analog information and signals the cooling fan switch to cycle the cooling fan on or off, as required.

If you are not the original owner, the previous owner may have bypassed the heater core. The heater core is like a small radiator that has hot water running through it from your motor. It is inside of your dash board, near your a/c and heater controls. That is how yur car gets hot air. The air runs through the heater core making it hot. Bypassing it is a cheap and quick fix for a leaking heater core. When they get a leak, they leak all inside the car down to the floor board. Check under the hood along the fire wall. If it is bypassed, you will see two hoses spliced together. One will be bigger that the other slightly. If this is your problem, you are more thatn likely need to replace your heater core
