While driving the left turning signal stays on. Tried removing one of the relays but was told there is not one. Put relay back in but now other relays are clicking and back tail light is draining battery. I am thinking relay is bad after I removed from PCM. I do not have a diagram of the combination module location and need to see why other relays are making a clicking sound. Please advise what needs to be done so no other problems occur.

The front control module is located in the integrated power module which is located under the hood, left side.I assume the relay that you removed was the park lamp relay in that integrated power module. I think you should have the trouble codes retrieved to see if there are any codes referring to that front control module and/or the steering control module, because the turn signals are actually data line signals sent from the steering control module to the front control module. I do see trailer turn relays, but the park lamp relay is #7 in this integrated power module diagram.
