Hello, first time owner long time reader

Recently acquired a 2014 Tacoma, had an issue with the rear differential, had a shop. Put all new bearings in the rear differential.

Before this had no other issues out of the truck besides a noise coming from the driver side rear. After this, if I clear all the codes out and I go over 67 mph, the speedometer quits working and the ABS, brake, and traction control off lights come on and then eventually the check engine light
Took it to a shop they replaced the VSS sensor on the transmission and both rear wheel speed sensors and it still has the same problem
That has all been ongoing for about a month now and then today the AC light started blinking and the compressor will not run more than 3 to 5 seconds and I have plenty of refrigerant in the system. Any help with these issues would be much appreciated

 

As for the speedo and dash lights- sounds like shop installed your rear wheel bearings/sensors backwards of each other. Just had the same happen to me a few months back.
