Temperature Gauge fluctuating and No hot air.
Last week I noticed my heater wasn’t blowing any hot air out, but my temperature gauge said 190 (normal)…then my temperature gauge went to 245 and hot air started coming out finally and then dropped down to 170 then backup to normal. (In town driving). Last night it did the same thing…sort of worried about it… Would this be a thermostat issue? No, hot air blowing out is where I get confused.
