You didn't happen to blow a fuse in the swap did you?

Do you have automatic temperature control (#'s around the temperature control ****) or manual (just red & blue around the temperature control ****)?

 

checked all fuses, they are good, there are numbers around the temp

 

And you've tried hitting the a/c button with the mode selection appropriate for the A/C to operate (either bi-level, vent, or defrost)?

 

selected a.c. it lights up but compressor want kick in

 

Can I assume that it is hot enough for the compressor to kick on and that the temperature **** is on it's coldest setting? Was the replacement HVAC control head new?

Could be a problem with the interior and/or exterior temperature sensor... A scan tool would help in diagnosis.

 

May not determine anything but let's establish something:
Remove cycling sw connector from accum and, with ac selected, ground each pin and see if clutch engages.
If it does, jump the pins and see what happens
