Do as LP has posted ..that will test the integrity of the high fan circuit and the fan motor itself. If still no fan , I would start with testing the feed fuses
The test for LOW fan [ a/c], is to jumper the pigtail leads at the high pressure sw..this will also test the fan motor along with the low fan circuit..
