Replaced radiator, thermostats and the fan assemble, why is the vehicle was still getting hot?

Thank you, Ken, for your help. First maybe I should explain I am the monkey in the middle here. I type better than my shade tree mechanic. Van was losing coolant. Found the radiator had a leak in the seal so we replaced it with a second one after about 3 years. The van started to get hot, so we replaced the thermostat. Next time we were out it overheated again, we live in the desert and vehicles get hot here. Under future inspection we found the A/C fan motor was no good. We could have replaced just the fan, but it was not much more money for both fans in the housing and lifetime warranty. Still getting hot so checked wiring. Fan relay was burnt circuit got hot. My shade tree mechanic ran a jumper wire from the fuse to the fan. It will blow the fuse I guess if there is a problem. Van has not overheated anymore but the A/C started blowing hot air and I was wondering if this is because the fans are on all the time and the A/C is not working as it should. Yes/ we did recharge the system with no changes. Thank you Ken, for your patience hope you can help.
