1997 Buick Skylark V6 3.1Ltr so a couple years ago the heater core went and it was bypassed at the firewall. over the weekend i had it fixed and i bought the heater core. now their is no heat plus temperature knob on the dash has some resistance and will rotate back a bit when turned and let go. i took it back this morning before work and the guy says it may be the heater valve, but i do not think there is a heater valve in my car. i say the air panels/diverters are not lined up right. the heater core seems easy to install(well, once you take the dash apart). it is only a mini radiator with two small pipes extending. it does not look like it is necessary to mess with any cables or flap/diverter doors. any ideas/suggestions? i just want to get some feedback because i am supposed to go back in saturday morning - maybe i shouldn’t. this guy is not going to want to go back under that dash. i may be better off finding someone else to fixe it. thanks for any insight
