93Rodeo

first off i have a 1993 rodeo 3.2L.I have two quick questions for anyone who may be abel to help.First off the other day i went to use my cruise control and it had quit working,what would be the cause of this,and what would i do to go about fixing it?
My second question is since i bought my rodeo the air conditioning hasnt worked is there anything i can do to fix this problem?
Thanks to anyone who can help me with these problems in advance.And thanks to all who helped me in my other post on the tapping noise i was hearing it was the tensioner.
Thanks again Les

check for a blowed fuse or vacume lines on the
servo unit under the hood may have cracked or
came off. as for the the a/c u need to make sure
it is charged and that the belt for the a/c
compresser is on the truck

good luck
