Now the whole cluster lights up. You can hear the compressor turning on but no air I already checked the blower fuses could it be a bad blower

Turn the A/C on and turn the blower dial to the max setting. Then check both contacts at fuse #43. If 12v is present swap relay K21 with a similar relay in the fuse box and see if the blower works. If not.............

Remove the panel under the passenger side, and access the blower motor. Using a DVOM, test the White wire for 12v and then the Pink wire for ground.
