As I was vacuuming my car and moved the passenger side floor mat and notice it was wet only under floor mat towards the lower sections of floor mat. every happen to you

 

What do you mean by the "lower sections of the floor mat"?

 

I'll take a pic

 

Nevermind it looks like it's coming out of the heatercore

 

I was going to say your only culprits would be heater core or evaporator box. Though I assume you're not running your AC in early February. But the "lower sections" wording confused me.

If it's your heater core that sucks because that's not a fun job. The whole dash has to come out to do the heater core. I've had my dashes out half a dozen times so they're fairly easy for me now but still no fun

 

don't let it drip for too long...the ECU might get wet from coolant.

 

To avoid that, I did a heater core bypass, since I did not have the time to replace the heater core. Before then, I became too familiar to the smell of coolant, and I put towels on top of the ECU.

 

Doing bypass tomorrow won't need ac till june. And I need to replace my Crack dash and guage. I don't think it's hard at all just time consuming.

 

What do you mean won't need AC till June? Your AC is irrelevant to your heater core.

Actually the dash is the easy part. The extra irritating part is that big center support beam needs to come out (or at least loose enough to move) as well as the much of the crap attached to it

 

O damn for real. Other them the nissan dealer where should I buy a heater core.

 

What I've been doing lately is getting part numbers from Rock Auto then buying the same part on eBay for cheaper

 

Here's an OEM for cheap

heater core time, I got an oem one from the junkyard that was in pretty good condition. I never did a heater core job in my life but the price the mechanics were charging here was outragous and I needed heat for the crazy winters here. So i took the time to remove the dash and everything attached to it. With the help of the org, I managed to do it in less than a day. I didnt have to remove the steering wheel or the center beam. Saved myself about $600.
