Try testing the brake switch (it is behind the brake pedal) for 12V and continuity between wires when engaged. You can also try checking the brake light relay. It is located on the fuse block.
i hope this helps

Since your blower is working and it is a heat issue,thats where we'll
start,First thing is have you checked the coolant level in the radiator when
engine is cold,make sure it is filled to top,next verify you have coolant in
reserve ,Start your van and get it up to normal operation temperature,If your
heat gauge on the dash works correctly it should be 190 degrees,Now lift the
hood and locate the two heater hoses going into the heater assembly at the fire
wall,Both hoses should be hot to hold on to,if both are hot and no heat inside
your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

I would try to replace the thermostate again, Sometimes these can get damaged in the warehouse. Cheap to try it again, $12-$15
