ok, first off check the radio or horn fuse to fix the radio, second off does the temp gauge go up at all, if it does then you have air locked in the heater core or you are low on coolant or i just thought about it the heater valve out in the engine compartment by the fan motor may not be functioning properally, and if your gauge doesnt go up then you need to change your thermostat.
third thing, the clicking noise, well my brakes did that too wheni first got it and it turned out to be some beat out bushing that the sliders ride in on the caliper, 20 dollar caliper and change the 2 of em to make the brakes work better....
fourth thing, you paid too much money for that van.. personally i would have paid 500 for it and no more.....
make sure you get that front end checked out for ball joints and idler arms....
