I have a '93, 4 CYL as well. I had to replace the heater core about a
year ago for the same reason. No Heat. It's not really that tough a
job and it sure made a differnce when we went to the tops of the
Colorado Mountains last Thanksgiving. Above 8500 ft and snowing like
the dickens we stayed warm and I have a rag top.

I would follow the previous advice on flushing the unit first to see
if that takes care of your problem. That could be the quick fix.

BTW, mine doesn't have a "valve" anywhere that I could fiind. If
someone could post a link to a pic I would appreciate it.

I had a 79 CJ that would not warm up the water in winter even with a higher
thermostat. I partially blocked the radiator and that helped, not that the
CJ had the best heater. Buy a TJ, great heaters.

Then you need to replace your thermostat.

If the enigne does not warm up, you will have no heat. Replace the
thermostat. On a '95 it wouldn't hurt to do a full cooling system flush:
install the flush filling ($6), use a radiator flush chemical per
directions ($4), drain the old anti freeze (disposed of properly, it is
toxic to dogs and cats), and refill with 50% mix top grade antifreeze (1
gallon antifreeze, mixed with 1 gallon distilled water, might take a bit
more than that)
