Overheating, + some issues, Need some help guys. Options

[creis]

So I got my car back from the shop Sat and it was all good, looked great. drove it to work today and all was good till on the way home, I stoped at a store to buy a battery for my door remote. and notived steam out the vent. popped the hood and the coolant was over flowing out the cap (not into the overflow take (well very little) started the car, and the temp shot up to 3/4 max but did not hold steady. drove it home gently, the temp guage went normal. got it home popped the hood and my radiator was cracked, figured that was the problem I lost a pretty good amount of coolant, so I let the crack dry out, and fiberglassed over the crack hopeing it would hold a little wile (ordered a new KOYO aluminum radiator should be here in a few days.)

any way let the fiberglass dry good and it did, started it up, everything seemed good, let it heat up filled the coolant everything looked good, fiberglass patch held good. drove it around for a wile, temp guage warmed up as normal and stayed normal.

got home and it was steaming again, fiberglass was holding but not 100% and was not (very little) overfloing into the side tank. and noticed the fans were not going on, tested it by letting the car idel for a wile then little reving, no fans at all, nothing. ( checked the relay and looks fine but I dont know much about telling a good one from a bad one)

what could be the cause of this, I did some searching and it could be the thumostat, but I dont undestand how my fans wont turn on.

any tips or knolage as to the cause, I'm gana try a few things tomarrow and hopefully you guys give me so good advise, but its probably gana go to the shop for a tune up and to see whats rong.

So I'm in the van again

oh and now just today 3 tail light bulbs went out
