Help!! P0500 Code, Parasitic Draw(?), No A/C, Windows, Abs Light, Trac, Etc..

Okay. Oh boy. Long time reader, first time poster. My 15 TRD OffRoad 5A has 113,322 as of this post. Zero issues ever until last week - the a/c randomly wasn't working and there was a bit of noise from what I assumed was the a/c compressor. Tons of play in the clutch, so I replaced the clutch and the a/c worked great for about 48 hours, but was still noisy.

Today I had to drive about 120 miles to go meet my girlfriend for her birthday, and 70 miles in the speedometer disappeared a/c died, abs, trac, tire pressure light popped on and then came the P0500 code. The weird thing is, I no longer have a working vent (no air will blow) and my windows don't work. Now the little noise is VERY noisy.

I replaced all the obvious fuzes (Mini10 a/c, A/C Compressor relay and steering wheel Mini10) when this happened, nada.

I saw in another thread with similar symptoms that a user had a bad alternator. Got my battery and alternator tested, battery good, alternator only read a .9. Replaced that on the spot, CEL went away. Nothing else worked, no a/c, no windows, abs, trac, tire pressure lights on.

Well I needed to get going so I drove another 20 miles, CEL came back on for 0500. I replaced the sensor itself, and truck is simply dead. I jumped it to get it started, but same symptoms ran on.

Any ideas? Runs and drives perfect, no hard shifts, just no a/c and no air coming.

I'm now stuck thru the 4th + whenever I can find a tow truck to get me 150 miles to the next Toyota dealership, sos.

 

Sounds like your IG1 No2 fuse is blown.
