Off the top of my head you probably have digital controls
the jump probably gave the heater relay a jolt of elec. which made it freeze open or shut
try disconnecting battery for 5 minutes and reconnect it this should reset relay
also heres something to look at even though it gets cold a hose could have split and slow leak on passenger side check floor for wetness if so take to nearest auto shop this needs fixed right away

i had a car that the relays froze shut so i had to manual start it under neith the car with a long screw driver cause key wouldnt start it

temp guage only shows temp not low coolant you gotta pop the hood and check manually the coolant tank for low fluid
even with low fluid the car would have heated up quicker so the idea of low fluid is a gasp heater would have heated quicker too
check condensor in front the small radiator infront of big radiator to see if iced up a little hose water sprayed on it should loosen the ice if any try to see if theres a way in mornings to see if you have any coolant leaks
coolant leaks can break a car into parts and be costly

Have you checked the antifreeze level if it gets low you wont get much heat at all

    that could also be due to low antifreeze coolant..check the level and see how low it is the temp guage should tell you its low on antifreeze.

Ac and heater both coming on just taking turns.


If this just started to fault after battery replace, I would suspect a vacuum hose or outside air temp sensor got unhooked or damaged under the hood. A scanner could help diagnose issue if nothing obvious is found to have been disturbed under the hood during batery replace.Good luck!

1995 Park Avenue heater A/C tempature reading flashes


one or more of your actuators is malfuntioning.  they ar eunder the dash.  I had a mechanic repair mine for about 400 bucks.  the dash needs to b removed and some very tight spots to work in.  the flashing is maybe caused from the sensor.  either outside air tempo sensor or inside. does it blink while showing the inside or ouside.  not exactly sure where the inside is, but the outside is in the center in front of radiator when u open the hood. black about the size of a tube of chap stick.
