heat works fine but no ac on 1990 Buick LeSabre

No ac at all just hot air blowing out

Asked by for the 1990 Buick LeSabre
The most likely cause for the AC to stop working on your 1990 Buick LeSabre is the system is low on charge due to a refrigerant leak. If the system is low on charge, adding refrigerant will can get the system up and running again. This may only be a temporary repair, If a leak is present it will need to be repaired or the AC will stop working again when the new refrigerant leaks out.
Thanks i will try to see wat the problem is
