i find it hard to beleive no one on here has ever had this issue with a zj before. please any info would help!
i figure the next things to do will be change tstat and flush it as my heat doesnt work at all, only the defrost does leading me to beleive a good flush is needed. if that doesnt help either im led to beleive that either my guage is just plain broken or its a wiring issue. any thoughts?

I might check the wiring around the temp sensor and the sender make sure none of them are jacked up.
So your defrost is the only vent that blows heat?

buy a 1kohm resistor and push/place that in the temperatur sender contact and ground it, turn on the car and it should show around 80-90 celsius. If not the wire to the gauge or the gauge itself is defect.

Does temp gauge move at all?

There is a vacuum reservoir under the battery tray, the hose could be rotted, the black plastic vacuum line could be eaten by battery acid. There is also a small black vacuum line right next to where the A/C enters the firewall, check those hoses and lines for the defrost only problem.

still not solved, BUTTTT i drove her home from my buddies and realized the upper radiator hose mount was cracked upon arriving home and actually i broke right off when i jiggled the hose to see how bad the crack was. so i just got a new radiator i should be installing this weekend. based on the size of the crack i dont think there was enough pressure for the gauge to work coreectly. is my thought process correct or?

I have a 93 grand and my gauge doesn't always work. My thermostat is new, water pump is new, the entire cooling system is new. The needle just goes back and forth between 210 and cold but motor is fine

got the new radiator in today and now its leaking from the cylinder head so i think i have a blown head gasket. any other ideas on what it could be that would be less expensive/easier fix?
