1987, 17,000 or so miles, did the major myself about a year ago... Was driving with my daughter, last drive of the year...car running great... it’s 55 degrees out here, chilly... Car is running great, but temp needle is always at the middle, or 1 mm over...odd, as it’s cold out side... At stop signs it nudges right, about 1-2 mm, barely over the middle mark. Get on the highway, goes down slightly, it still above the middle by a mm or so... I turn on the heat, as it’s getting cold in the car. Heat doesn’t work, BLOWS cold?! Press all the knobs, no change. Odd, as it worked after the major when I bled the system... Park the car...temp shoots up to the 3/4 mark. Fans do NOT go on... double odd...heater still blows cold... Wtf??? Checked oil level, normal, no intermixed coolant Checked coolant, normal, no milkshake... Checked connectors in the frunk... normal, no burnt connectors... Now I know this can be 2 separate issues, but what would make the heater blow cold, and fans fail? The heater blowing cold throws me. Electrical issue with a valve somewhere? Air bubble??? Plan next weekend is to jump the fan relays, make sure they work. I also think there is a temp sensor in the right radiator. Need to jump the sensor see if that works too. But again, the lack oh hot air throws me? This can’t be a stuck thermostat, can it? I would think if it were driving wouldn’t bring the temp down... The water pump impeller couldn’t have worked loose, could it? I would think that would cause catastrophic overheating, moving or not... Any help appreciated.
