Ive been troubleshooting the heater in my 94 Camaro. Ive replaced the core, the heater lines and checked the hoses. The heater core gets hot, the hoses are hot, everything is working fine in those areas. I pulled the kickpanel on the passenger side and checked the blend door and its working fine too. I pulled out the ole chiltons manual and it said in bold letters please be sure the insulation is in place. Well that was part of my problem, so I put insulation around all four sides of the core and around where the hoses go out into the firewall. Im getting more heat, but not the full potential. Some how air is escaping out into the engine bay. If I turn the fan on full blast you can feel air shooting out the area where the heater hoses are in the engine bay. The air shoots out into the engine bay regardless if I have the heat or AC on. I checked my 98 firebird for a refrence and no air shoots out by the heater hoses on it, so I know something is wrong. Any body had this problem? Thanks.
