Yesterday, after renting and towing a wood chipper, my AC stopped working and I get the message (Check Connection of Air Conditioner", and I have no turn signals. I checked the hazards, and they work, but nothing when I use the lever on the column.

After researching on Club Lexus and here, I saw a relay issue for the AC. I swapped relay's around in the panel for the Fan and Magnetic Clutch, still no AC.

For the turn signals, I checked the fuse under the hood, and its good. Where is the flasher relay located? I don't have an owners manual, and I cant seem to find a good description of where to look. Any suggestions?

If the AC relay is gone the button will flash.

Thanks for the thought, but I don't have an A/C light since I have Nav.

Here is the message I was getting:

as an update, tonight I found the blown fuse! I have turn signals and HVAC again!

When I got home from work, I took my multi-meter (which admittedly I barely know how turn on) and set it to Ohms to start checking fuses. I went about touching the exposed leads and all came back reading 0.00. Frustrated, I tried swapping relays around, to no avail, still no turn signals or HVAC. I had to go help my dad, so I left it alone and ran to my parents house. I took my multi-meter with me so my dad could show me (again) some basic functions. I described my method to him and he said I had to remove the fuses to test for continuity, as when they are in the fuse block you have know way of knowing what you are testing in the circuit.

When I got home, I went about pulling EVERY fuse under the hood, and in the driver side interior block, ignoring what the description said the fuse was for. All the fuses under the hood were good, so I moved to the inside panel. Half way through the fuse block, fuse 55, a 10 amp fuse labeled IG1 NO.2 was blown. I swapped in a new fuse, and then for good measure and piece of mind, checked the rest of the fuses. That was the only blown fuse, so I hopped in, fired it up, and hallelujah! I had turn signals and HVAC controls again!

After it was working. I remembered downloading the owners manual from the TIS website a friend from Wasatch Cruisers referred me to, and looked in the part I printed regarding fuses. The description is for Rear air conditioning system, inside rear view mirror, nothing about turn signals...

At this point I am just happy to have it fixed, with a 10 amp fuse I had laying around.

Hopefully this helps someone else that has the same problem as the description for that fuse is not adequate in tracking down the right circuit.

Thanks, exactly the solution to my problem!

Buddy's rig had the same errors plus airbag light came on as well, this same fuse was the culprit. In his case it seems a corroded trailer connection may have shorted the fuse. Thanks much!

A million thanks for this post! Was having the same problems that you described. Absolutely tried every fuse that I thought it could be based on the owners manual. Would have never guessed it would have been this fuse based on the description. Sure enough fixed the issue. Thank you! Man I love this forum!!

Four and a half years later, your post helped me big-time today!!! I can’t thank you enough! Problem solved.

This was my problem as well!

I made the same diagnostic mistake: I used a continuity tester on the fuses while they were still plugged in and that particular fuse tested out good while plugged in. Doh!!!

TLDR - remove every fuse and test it because testing it while it’s plugged in can give you a false positive result!
