Hello,
Last night it was 28 degrees out and I drove my 97FZJ for 3 hours round trip. Heater was blowing luke-warm at best. Temps from my Scan Gauge II fluctuated between 175 and 177 degrees during the entire trip. I've searched the forum and see where it could be the control value, heater core plugged and or thermostat. Do those temps sound normal in 28 degree weather and should the heater blow hot at those temps? Also, I will search for information on the control value. While I see recommendations to check it, I don't see any guidance on what I should visually be looking for. Does the 174-177 temp help narrow it down to possibly a thermostat? Any suggestions would help.
Thanks
Robert
