Horn Assembly problems of the 2011 Nissan Titan

The first issue is the a/c system. When the system is being run on the maximum setting there is a audible ticking sound. This sound has been attributed to a part inside the ac unit that's made of plastic that goes bad really quick. The result of this is no ac or no heat and a very expensive cost to repair. The entire dash has to be removed to accomplish the repair. The second issue is the (bcm) body control module. This module controls all the accessory electronics inside and outside the vehicle (tpms, door locks, horns, lights, turn signals, windows, trailer hitch etc. ) Nissan knows this is an issue because of the hundreds of post online about various models of their vehicles with bcm issues. However they have not fixed the problem. There are hundreds many thousands of vehicles that don't have working electronics because Nissan hasn't done a recall and the parts of too expensive for the customers to fix. My vehicle is a 2011 with 58000 miles and none of the door locks work when trying to use the key fob. The tpms comes and goes whenever it wants to. I've had the system reprogrammed and the issues still remain.
