heater core??? help???

[mattlikesinfiniti]

hey guys i know i haven't posted much of anything for a long time, but i was wondering if any of you guys knew what side of the dash the heater core is in my 96'

thanks a bunch, matt

should be on the pass. side where the blower assy is.Somebody should chime in soon that knows for sure.

it's near the middle on the passenger side, open the hood, look at the firewall (on the back of the engine), you should be able to see 2 clamped coolant hoses going in past the firewall, they connect to the heater core.... i hate to be the barer of bad news, but it is a real PITA to do this job on most nissans, you might have to remove the whole dash, disconnect everything till you get there (including steering column, and passenger side airbag).......i've seen the heater core replacement being done on a 1993 300zx and a 1998 maxima

i really hope that you wont have to go through that (i know that i'm going to have to do it soon), and i wish you the best of luck...... please post as many pictures as you can

thanks a lot for your help guys, i think thats possibly the reason why i'm not getting any heat or air conditioning, but if i ever decide to get around to do that i'll document it

Heater core shouldnt effect AIr conditioner ??

Is the Blower blowing ?

[mattlikesinfiniti]

there's air blowing, but i feel like this its just air from the outside, i was told the heater core or watever might be it, but any of u guys think otherwise?

[yodawill2000]

When you switch from AC to heat do you hear the sound in the dash from the , Heck forgot what its called. Its the flap that redirects air from the heater .

i dont hear anything

ok..... Check coolant first, if it is up to level (or appears to be), then the next thing to check for is if there is any coolant smell in the cabin, or if there is any liquid that is leaking into the inside of the passenger cabin (take out the floor mats, check for wetness, there shouldnt be any if the heater core is good)

if all is good, the the problem is that your heater core is cloged, or that your air box doors are not operating properly

the heater core can be cleaned while still installed (if it is in a good shape), just take out the hoses that connect to it from the engine bay on the firewall (tight area but very doable, and you will need to drain 2 liters of coolant before you start the procedure), then hook up a high pressure hose into one end, pump air or water into it (from the left heater core pipe if you are looking at the car from the front, if nothing comes out, then try from the other pipe that is on the right side), that should clear up any junk that is piled up over the years, then install everything back and test it............. i must warn you though, if the heater core is about to go, then it will start to leak when you pump high pressure air/water into it, which will make changing the heater core a must....... i hope this helps, good luck

My bet's on the mixer door, or its motor.
