hint if compressor won't start it may be out of Freon, if that is case then there is a leak and should be fixed...... see pic ac compressor relay behind right headlight

it may have a slow leak which is seasonal that is quite common. if not recharged eventually to low for compressor to start. your pic is nonspecific as to which relay is compressor

It looks like it #5 in the description. Can you double check the year, Mitchell1 does not show a transport for this year.
