Well, as people read in my other thread about the heater core, I replaced the heater core. (it WAS leaking) My windows are STILL fogging up, sometimes worse then before I changed the H/C. It happens when I drive, and after I shut the car off. I used to see steam coming out the side window defrosters after the car was off, now I don't. Could it just be the old antifreeze which I wasn't able to wipe out of the heater assembly? (Why would it be worse?) I'm gonna try bypassing this heater core to see if anything changes but Idk when I can get to that, time is tight. (trying to get back to work) Any other ideas?
TIA

Check proper A/C operation... That is why when we defrost, the AC automatically comes on, it is because it is trying to remove the moisture in the air faster.

Thanks, the A/C was working perfect before I changed the heater core but during that disassembly I had to drain the A/C and remove the lines off the blower unit. Today I did wash the windows to get the old antifreeze off. After that it was only a minor fog near the defrost area.
Now the car died from something else so I can't check anything till I get it back running again.

windows still fog due to residual in the vent system...good luck getting that out of there

Thanks for that sarcastic remark. It made me laugh after this bad day. I was thinking that and I should have taken the heater unit all apart and dried it but I didn't think of it while it was out.

Oh well, I gotta have a sense of humor with this b/c I guess I need to take this dash out again to get the heater out, right down to the firewall. Eh, it wont be as time consuming and such a PITA the second time around. Yeah, fun for me again. Good thing I didn't go back to work yet. LOL

maybe u can get it out of there without removing the entire dash.....do some research first

I just did it over the weekend to change the heater core so I know exactly what needs to come out. There is NO shortcuts on this one.
#7 on this one https://www.clublexus.com/forums/ls4...ater-core.html When I had it out I wiped down under the heater core but not completely dry. I didn't think this was gonna happen.
