Having problems with your 1995 Nissan Altima ?
My heater will blow air, then not blow air, then work very weak. Do I need to just replace the blower motor?
Its very possible, the blower motor is under the passenger side of the dash and next time its hanging up and running slowly find the lump sticking down and give it a a light to medium strength hit with a rubber hammer or something comparable. if it picks up and runs right you're looking at a bad blower motor if not it gets pretty complicated from there and you may need to seek a local mechanic.
Sounds like bad switch contacts, it's quite common on fans and heaters and likely given the age of your car and discribed symptoms, try wiggling the switch, then turn swich on and off quickly a few times, I'd have this checked first.
