Heat/AC not working well

Hello all,
I have a '96 Dodge Dakota with a 5.2L and around 230,000 on it. My blower motor used to work on the three lowest speeds, now it only works on the lowest two. The air coming out is only a few degrees warmer than the outside temperature. My A/C works about as well. I replaced my water pump and thermostat last year, but that had no effect. Any ideas?

You have 3 entirely different problems. Pick one for this question and you can start new questions for the others. It gets way too confusing with people changing subjects.

With the engine at full operating temp, locate the 2 heater hoses where they go into the firewall and feel them to see if they are both hot to the touch. If not too hot to hold, then you have to look at the actual engine temp and if that is up, if it is, then your looking at a restricted heater core.
If you find that they are both too hot to hold, then the heat in that vehicle is controlled by a blend door that regulates heated air flow. it is operated by an electric motor/actuator. The problem can be that the actuator is stripped or inoperative or the door itself could be damaged. This is what needs to be determined by examining the actuator and see if it is responding to heat change commands or not.
If they are both not too hot to hold on to, then you either have a restricted heater core or the system is not completely full and getting air pockets for some reason.
