hope this is in the right spot...

i bought my mini couple weeks ago knowing it doesnt have a heater. well in my eyes there is 4 things that control the heater

1. thermistat
2. heater core
3. fuses
4. coolant

so i said ok no problem i can figure this out. well first i figured since my car is race prepped they bypassed the heater core (still not rulling this out yet) well my buddy just looked at it today and he thinks its still hooked up.

i checked all my fuses and they seem to be right.

coolant is fine no problems there.

thermistat ok i think? doesnt over heat or anything like that holds tempeture well.

so what else can be my issue?

this is my only fault to my car and really wanna get it fix asap.
