So I have a 97 zj and the thermostat it indicating my jeep is over heating but I have enough coolant and my oil level is good. Another thing is that the heater is turned on full blast but it's blowing cold air. Any suggestions?
If you coolant system is full and you have no heat and you're overheating, it's most likely the t stat is stuck closed and needs to be replaced. If you have a mechanical fan the clutch could be bad not engaging the fan when it gets hot. But I'd lean more to the t stat.

Yeah the fan good. Another thing that I noticed was when is was really cold whenever I turned the heater on before it started acting up the battery gauge slowly went down the longer the heater was running. Do you think that could have anything to do with that or just take the battery in for a recharge? I appreciate the help you guys are giving.

Convention led acid batteries do not like to be fully discharged. If you have a good battery tender you can try to trickle charge it for 24hrs or so.
