    2012 Tacoma. I replaced the A/C clutch sensor and the fuse and still no a/c and light still blinking. What is the next step? I REALLY don't want to go to the Toyota dealership. Any help will be greatly appreciated!

    Pull the plug at the compressor itself with the vehicle running. If you have around 14v its probs the sensor thats built into the compressor, which means its time for a new ac compressor. Ive also had ac’s work fine after clearing codes that were logged in the cars computer. So first check power, if you got power then clear all your codes. If its still blinking, replace the compressor.

    Edit: i see you replaced that sensor, have you evac recharged the system? Does the clutch even spin? Could be overcharged severly. Had a nissan yesterday with a whole water bottle full of dye in the system and after dumping it out of the low line and recharging it worked fine.

    I noticed the compressor isn't kicking on so next I'm going to ck the refrigerant. btw, I'm a woman and not a mechanic. I'm simply trying the things I can do before big bills with the Toyota Dealership.

    Okie dokie! More things to ck after refrigerant check I'm going to try the refrigerant in the morning and go from there I'll let you know the results (fingers crossed). You are a great group to offer help and I'm thankful
    Additional note: The guys at the parts place were laughing, because they have had Toyota people in all summer with the same problem

    OP, when was the last time your system was recharged? If it is on the original charge from '07 my efforts would take me first to a low charge. You can do this quick check and see if it may possibly be a low charge issue. Open hood. Located on the metal line coming out of the condenser toward the firewall is an electrical switch near the radiator but high up toward the passenger side. The switch is a high/low pressure switch and serves to kill operation of the compressor if either too much pressure or too little.

    Disconnect the electrical connector itself from the switch (Do not attempt to unscrew the hex nut part of the switch; leave the switch alone and attached!!). The connector will have just two wires: probably a white with black stripe wire, and a beige wire. With the electrical connector off bridge the two terminals within the connector with a short wire or paper clip and start the engine and activate the AC. Does the magnetic clutch now engage? If so, that tentatively points to low charge or bad pressure switch.

    Nothing worked. Had a mechanic look and he did all the things y'all suggested+ How much does run to get the Compressor replaced at a Toyota dealership?

    Did the mechanic say the compressor is shot? If he is not sure, take the truck elsewhere, but not to the dealership $$$

    I just went ahead and dropped it off at the Toyota dealership this morning. It wouldn't take the refrigerant. We tried everything everyone suggested. Stay tuned and I'll let everyone know what it turns out to be

    I have a 2010 tacoma flashing ac light. Fuses all good relay is good. Clutch not engaging. Applied power at relay and clutch engaged light still flashing and air still warm. Relay not receiving ground from amplifier to energize. My pressure switch has continuity, suspect amplifier.

    Appreciate any thoughts, thank you.

    Sounds like compressor, clutch, flush system and evaporator?

    Find a small mom and pop shop.. Don't say or show anything that the dealer said, is bad. Have them tell you what's wrong and give you a quote

    Yep, all 3. Already had someone else look at it and said it was probably that. Toyota would need to repair it.
