There is no expansion valve. There is an orifice tube in the high side hose where it connects to the evaporator inlet fitting. You'll have to let the freon out first to open this connection. Use needle nose pliers to grab the orifice tube. If the screen is plugged with aluminum mud, there are more serious problems with the system that will have to be addressed. Of you don't have the tools , a vacuum pump and a gauge set, I'd let a A/C shop do the job.
