Ac blower not coming on - help

AC BLOWER IS NOT COMING ON, COMPRESSOR OUTSIDE DOES COME ON. Got 28v ac at all the thermostat wires except one (as i remember).. does anyone know which wires to jump to make the fan come on without the thermostat. Tried fan on switch (auto or manual) and that does not work.. i'm just trying to make sure the thermostat is not the problem. thanks.

Moved you to a fresh thread. Also had to remove your contact info in the post, it's not allowed.

Sounds like it could be the run capacitor for the fan. Is this in a furnace or air handler? The capacitor can be checked if you have a volt meter that can check capacitance to see if it is within specs. I have attached a photo of a run capacitor. As far as jumping wires you can remove the face of the thermostat and use a jumper between the "r" and "g" terminals. You can use a paper clip if you don't have a small wire handy.
