A couple of problem I could use suggestions on - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have 2 problems (beyond the swiss cheese sheet metal).

#1) Everything Electrical works fine at higher RPM; at Idle, the turn signals flash VVVEEEERRRRYYYYYY slowly, the heater fan comes on and off (only when on hi, could be due to a worn out relay) and all the light inside and outside get a little dim. Is this most likely an alternator problem, or is there somewhere else I should check first?

#2) Summer: Truck runs hot, new thermostat and water pump, still runs hot. Winter, temp qauge right where it should be, only get hot air out of heater at higher RPM, not very hot at that. Just a radiator that needs to be flushed?
