ok i got some problem on my integra(DA)!
this is wants going on, my corner lights keeps blinking not the bump
lights, and my heater is not working too(its not even blowing heat and cold air) same with the defoster for the back window! need help cause winter is coming u soon! i check all the fuse aready!

 

Signal lights - keeps blinking when the switch is not on?

Heater - if the climate control is all the way to the red and its still not blowing hot air. check if theirs a coolant line running to your heater core.

Defroster - check the defroster lines on the rear windshield and see if any of them is broken

 

soory not to thread jack but where is this heater core

 

heater core is behind your dash right in the middle, if you look under the dash in the middle you will see a platic box underneath, the heater core is inside of that box...
