im 92% sure i didn't. Temp gauge worked after i did the thermostat just stopped working after i did the heater core flush.

(1993 loyale ea82) Can anyone help me out? i was having heater issues so i replaced my thermostat yesterday, didn't fix the heater but it did cool down normal driving temp. Then today i did a heater core flush using a hose and water, once i got done with that. it did fix my heater issue but now my temp gauge isn't working. it moved maybe a millimeter after idling for 5 mins, taking it on about a 3 mile drive, then i let it idle for another 5 mins and still only a millimeter from the temp gauge. I checked the temp sensor to make sure i didn't unplug it by accident and it appeared to be plugged in so i re-plugged to be sure and still temp sensor faulty Any advice is welcomed! ty.
