My blower on my heater doesn't come on every time some times I have to hit my dash. Then when it runs it won't push full air out, as well as cutting out when I apply brake or go around a corner. It doesn't seem to work unless its on high as well. Depending on what is wrong depends on where I take it. Just put $ in it for a few other thugs so now I'm a broke folk. Any suggestions would b appreciated

Check for loose wires at blower and control panel. The dash may have been off and things werenot connected correctly. Also check ground wires. To dash.
