Hello and welcome to justanswer.com
You may have a problem with the electronic cooling fan assembly. There is a built in module that may be failing. To be sure it would need to be tested using the Ford based factory tool. For the ABS warning that module will need to be scanned for the stored fault codes. I see issues with the front wheel speed sensors causing this and since the warning will reset after an ignition cycle it is usually an electronic component. I have also seen issues with the ignition coils. They will cut out intermittently and spike the PCM causing other warnings and symptoms. AGain a complete system scan is recommended. As far as the dual climate control problem this is usually a sticking heater valve if the problem comes and goes. The DCCV is the main component controlling the heating and air conditioning. The valve controls the flow of coolant going to the heater core. When on a/c the module will pulse close the valve so hot coolant does not enter the core. Also if the module loses the power from the valve it cannot close it off so the valve will default to full heat. Lastly I have seen sticking valves short out the control module. If you take it to the shop do not authorize any repairs until you get back to me with their diagnosis and cost estimate.
