Double check fuses and then perhaps the actual switch? Make sure blower is properly grounded.

is their any way to test the switch ??

See if you are getting power at the motor connector. Then you vcan open the panel switch and manually press the microswitch to test if the blower is working.

my blower is working but no heat is coming out...gotta love it...the timing on this is just hilarious. All ways happens when you need it, right! Still trying to figure out what is going on.

Are you not getting airflow or not getting heat? If no airflow, check your cabin filter. If the heater hoses at the firewall, driver side are not heating up, you either have a coolant blockage or an air bubble.
