There is no replaceable fog lamp relay. It's built into the digital instrument panel junction box (IP) and switches power using an intelligent power switch (power transistor) that's soldered to the board. When you turn on fog lamps the body control module sees the signal from the fog lamp switch. It sends a digital signal to the IP which tells the IPS to power the fog lights. You need to use a pro scan tool to see if the Body control module is receiving the fog lamp request and then see the IP is receiving the command to switch on fog lamps.

{: ) If the airbag light goes off after that 7 blinks (some are 6 or 8), that will be normal. The airbag module will blink the airbag warning light on the cluster while performing self-test during initial start-ups. After the self-test and the airbag module did not detect any fault within the airbag system, it will turn the warning light off. If the airbag warning light continuously blink or stayed lit after the expected elapse time, then there is really a concern and you need to double check the airbag system with a scan tool.

Check your ground wire. You should have a wire going from the case of the alt to ground. If there is none, get a decent wire and find a screw on the alt and then to ground. If that stops the warning light, get a good wire on good grounds. Is this a new or refurbished Alt ? The regulator is built in on these. Get a volt meter from a friend and see if you are putting out 13.8V when running and it's a solid 13.8 volts. Could be a poor fuse connection (they have fuses but usually soldered into a bump in the wire) or something like that.

Does it crank over and not run or does not crank over at all? If it cranks over then spray some starter fluid down the throttle body. If it starts, then you have a fuel problem. Check your fuel pressure. Some of these v6 require at least 45 psi to start. If it does not start, then pull off a plug wire and check for spark.

Turn Signal switch in the column is bad.

Will not crank over at all or cranks but will not actually run ?

The light staying on while driving is due to one of the door jamb switches is malfunctioned and more than likely going to be the driver door. For the reason being is that's the door that's mostly used than any other on the vehicle. If memory serves me correctly, the switch is located on the inside the door at the lock actuator.
