heater core hoses

heres my story back on jan 11th i had to have my heater core replaced at a well known national shop i know iknow i should have done it my self but it was frezzzzzzzing cold out. So they replaced it. Last week it started to leak so i took it back to them they replaced it no poblems there. NOW I HAVE NO HEAT there is heat at idle but not going down the road i looked and it looks like the heater hoses are on backwords meaning it looks like the on thats on the left should be on the right . I did check and there is coolant im pretty sure there is no air pocket i drove the car about 50 miles since also when i got it back home from the shop i opened the rad cap with engine running never shut it off the coolant was not hot i put my finger right in it . Its a 1994 camaro v6 3.4L . So my question is this could somebody send me a heater hose diagram or take a pic of there heater hoses at the heater core and send it to me. I did call the shop and they said it must need a T-STAT now the car did have heat b4 they replaced the heater core any help would be great thanks

Reversing/switching the core hoses will only let coolant flow the oposite direction through the core..

It will not cause there to be a loss of heat..

You either have a clogged rad or more than likely you have an air pocket issue and/or a thermostat issue..

If you mileage is high could even be a bad water pump starting to show..
