Washed my 1970 280se (134 converted) last night, and AC blew cold the 3 miles I drove it after.

This afternoon I get in the car and the AC was blowing not very cool, and after 10 minutes was just tepid

Fuses are good, and compressor is engaging.


Anything else to check before I take it in to have AC psi checked?

Thanks
