A/C Problems :( 1993 SL500

[rellik]

its getting real hot here in virginia and my A/C is deciding not to cut it in my SL500

if it isnt too hot out and i have parked my car in the garage, away from the sun, the A/C will blow cool

if it is more hot and especially if i have the car parked outside in the heat for a while, the A/C will do nothing and end up blowing the same temp as outdoors

my car has also been running slightly hotter than usual but nothing extreme, it hovers at 100*C and pokes above in stop and go, outside temps are 90+ so i think thats normal

thanks for the help
