The blower wheel went out because, somehow a tiny metal screwdriver got into it. Also the resistor is out and my AC isn't as powerful as it should be. Could that be the cause? PS sorry about the grammar I'm on my phone.
Sounds like all these things are unrelated to each other. Unless you damaged the evaporator (cold coil inside the car) while changing the blower you shouldn't have had any leaks. BUT if you put the wrong screw in the wrong location and forced it in then you might have punctured the evaporator. One has nothing to do with the other unless you damaged something (or that screwdriver managed to puncture the evaporator). The resistor pack is for controlling motor speed. If your blower isn't running on high, perhaps you miss wired something. But generally I'd not expect that to be the case. The other alternative is that the resistor pack (also not related to the blower failure or the leak) may need to be replaced. Maybe that screwdriver damaged THAT. In short, if the refrigerant leaked out - you have a leak. If the fan isn't running on high - you have a motor speed control issue. 'av'a g'day mate. )
