blower doesn't run with a/c

Good day all.

I have a split system; ele. furnace inside ac unit out.
and a new hunter t-stat.

during the winter I had a sequencer go bad and after a little poking around I was able to make the needed repairs to get the heat going, everything was working well up to this point.
after the repairs were made the fan ran all the time in auto, and cycled with the heat when in on position, no real biggie, I had heat.

However, now when I tried to run the air today my outside unit did good but no blower fan in auto or on. and yes the coil did cool quickly so i cut the unit off so not to damage it.

I wired everything just as it was before so I am thinking that when the sequencer let go it fried something else.

can I jump terminals at the t-stat to make the fan run so I can cool down? if so witch ones??

also,, I did change the t-stat in the winter when this first happened but no difference so I do believe the stat to be good

thanks in advance for your help

At the tstat jump R TO G. If you get blower its in the tstat. If not go in the furnace and check the fan relay out.
