Found the source of the leak. The line comes from the ahc pump which isnt really connected anymore but might still have fluid. Should I just disconnect and drain the line since the ahc system was disconnected.

Red/pink coolant.

Hello, Theres a yellow/green thin oil leaking from the passenger firewall area. I couldnt really find the source yet. It seemed pretty far down by the frame and ac lines. The brakes are working normally and the ac still blows pretty cold. Not sure what it is. Any help would be appreciated. Also...

i got it figured out now. For some reason I thought I had to remove the old power connector and only use power from the cigarette lighter. But after combining both and soldering it up, the climate control module has good power and works now.

I don’t have a fix yet. I took it to the dealer and they said theres a module or power supply that isnt giving enough voltage. I tried giving power straight to it from the cigarette lighter wiring but then I got an issue where the fans and compressor do not turn on. I still have more digging to...

My 1998 LX470 developed an issue last year where the climate control module had intermittent power. I had the head unit refurbished with new buttons and lights as well as having all the connections checked. It still continued. I took the car to the Lexus dealer and they said it was only getting...

Somehow my fusible link cover went missing and I am looking for another. Its the cover for the small fuse box attached to the battery. I know I can buy the whole block but just seeing if anyone can part with just the lid. Thank, Nk

No I have not found the issue yet. When mine cuts out, the fans and everything else cuts out too.

I’ve also noticed turning the lx on and off sometimes gets it turn back on but not every time.

The main ground cables seemed a little corroded so I got the three upgraded ground cables from a member on here but Im still having the same issue with the climate control. Any ideas before digging into the wiring behind the dash?

I checked the battery/fusible link fuses which seemed a bit corroded so I replaced them and cleaned all of the connections on the battery ground and cables. I also went through the fuses which were all good. There was no resistance across the battery/cables and the battery was 12.6v. The climate...

Also, does anyone have a pinout diagram or wiring diagram for the climate control unit?

After reading through a few posts and not really finding any definitive answers, I thought I should just make a post and ask. I have a 98 lx470 that recently developed a loss of power or maybe a bad ground to the climate control unit. Both the temperature sensor for outside temp and the climate...

Hi so I am having a similar problem. My 1998 lx470 has been having similar problems with the climate control unit too. It is dead most of the time and comes on sometimes. I had the control unit rebuilt and had the module on the rear ac checked and was told that all of the contacts were good...
