I HAD MY HEATER CORE REPLACED AND I HAVE NOT HAD HEAT SINCE IT WAS REPLACED

1994 GMC Sonoma

I had my heater core replaced and I have not had heat since it was replaced. I have replaced the switch thats controls the heat but that did not work.

Are both heater hoses going into the heater core thru the firewall getting hot?
