first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all. The first thing i would check is if the fan motor is blowing any air at all. If not u need to put in a new heater fan motor. first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all.

My 1998 Nissan sentra wony shift into high gear
If a 1995 Nissan Sentra will not shift out of first, there could be a problem with the throttle valve cable. The transmission could also be damaged.
the slave cylinder is bad
You need to warm the car up with hot water.
Your heater core is likely bad
check heater fan to see if it is working.
Likely heater core. I had same problem with 1996 S-10 with 4.3L.
Have you checked the 30 Amp fuse ?
Low coolant? Thermostat not opening? Plugged or restricted heater core? Heater core airbound? Heater valve control cable detached or broken?
tps or idle speed motor
