Just got a 94 S10 blazer yesterday - coldest day of the year too - no heat - the fan doesn't blow and there is no heat coming out anywhere - I looked under the hood and there are two copper pipes on the left back side that run I am guessing into the cab - one has a black hose attached the other doesn't - is one AC and the other heater core? was hoping to maybe to put in this Glass something or another until I can get it to a shop? It's freezing here and due to get colder - Seattle
Optional Information: 1994 Chevrolet S10 blazer 4.3L vortec
Already Tried: nothing
