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

i had the same problem had to replace the turn signal switch....GM for some reason wired the brake lights through the turn signal switch. to check if this is the case with yours. put some pressure on the turn signal lever as if you were going to turn on your brights and press your brake pedal and see if the lights work at that point that is how i found mine. hope this helps. if indeed they work with pressure on the turn signal lever. the new switch cost me $60 at autozone and that is with the steering wheel radio controls, make sure you get the proper switch should be part# sw771 if you have the radio controls on steering wheel and you will need a steering wheel puller and lock plate compressing tool.

SOURCE: front driver side turn signal light doesn't flash

replace flasher......usually located in fuse block area...listen in this area....select passenger side ...then select driver side...you can hear flasher clicking...you have seperate flashers for each...FLASHERS are small cubes plugged into fuse block....probable bad driverside flasher
