EGR Valve Vacuum Line and A/c issue
 

I just bought this 88 GMC 2500 with a TBI 350 love the truck but Ive been going through the engine and checking it out. Truck is in great shape for the year has 140k miles.

The egr vacuum line coming off the EGR valve is broken and it seems like they plugged up the line somewhere.. where is it suppose to go?

and also the A/c and heat worked great in the truck but I shut truck off at gas station and when I started back up the blower didnt work and the AC compresser no longer engauges I looked at all fuses and all are good... is there a relay somewhere? any other ideas?

Thanks
Jason
