Replaced all three switches and blower motor because I didn't have any heat now blower is working but not getting a strong flow of heat and it doesn't seem to make a difference when I switch from the positions floor defrost or other positions

you have managed to disconnect a vacum hose either under the dash when you instaled the blower or you have disconnected the vacum hose under the hood close to the firewall look for ths hose it is a very tiny vacum hose!!!!

this is what is called a factory default. for safety purposes if there is a problem with the wiring in the climate control system it defaule to the defrost position so you can see out the window. this can be a pretty tough job, the whole dash may have to come off. unless you well versed in automotive diagnostics and troubleshooting, and have the right equipment, I would take it to a local automotive technician.

There is a vacuum leak under the hood. On the 4.0 liter it is usually at the intake manifold near the brake booster. The 90 degree vacuum fitting pops off of the nipple of the intake. On the 5.2 liter the vacuum leak is usually near the battery where acid corrodes through the line as it passes near the battery box to the reservoir under the box.
