I have a 1997 mazada 626 and my heater is not working?

Check the heater core. Is there fluid on the passenger side floor dripping up near front?
Or it may be a faulty thermostat.

yes

yes fluid is dripping from the driver side

Heater core. Get a mechanic or pick up a Chilton manual.

Get ready to pull the entire dashboard to get to that heater core!! Happy New Year!!

Actually, it’s really not something you want to do yourself. Last heater core I blew, it was worth the $400 to have someone else do the dirty work… and that is about how much it runs too.

Oh, and I hope for your sake that you don’t have an automatic. The CD4E in the older 626 was failure prone; they tend to need replacement every 40,000 miles (unless you get a heavy-duty transmission cooler installed), and transmissions are not cheap!
