Question about Ford E-150
You have fried a relay from letting the + side of the circuit touch ground. Your blower motor relay absorbed most of the "shock" and needs to be replaced. I have attached a picture of what It may look like. As far as the climate control, I believe it is wired to this same relay, if not you have a blown fuse for power to it or another relay that is now defective. I have read this post and was trying to get an idea of a place for you to start, without tracing individual wires with a voltage meter. The relays are not expensive to replace, however you may want to keep in mind that the solution can not be answered on this post without "hands on" diagnostics. Your relay box is located under the hood, with a removeable cover. Hope this helps.

Thanks for using FixYa. P1633 means KAM voltage is too low. Further it means that maybe sometime in past the battery voltage was below the specs at the PCM. The code is just a indicator for us to know that the computer learns as you drive and all the code is saying is that it lost its power to itself and can loose that learned information. The battery provides 12 volts to power everything, the car probably sat for a while and probably took a long time to start or had to be jumped off to start.... when the voltage got below 9 volts it set the code. May be you can take it to a mechanic and have him inspect the battery for being weak or is about to get dead, also make sure to check your battery connections. Please do accept the solution if the issue is resolved or else revert for further assistance.

Usually the first thing to inspect when the blower fan stops working is the fuses to see if any are blown. Locate the 10A cluster fuse or the 25A HVAC fuse in your car manual, and examine them to determine if they need replacing. The car owner's manual will tell you where to find the fuses that are connected to the heat and/or air conditioning. On the interior fuse panel of the car, a 30 amp fuse is labeled "Heater" or "HVAC."
