    '10 4WD reg cab
    fog lights (with OEM switch), skid plate, stainless exhaust tip, Curt receiver hitch, Exact-Fit seat covers, AFE air filter, intermittant wipers, EGR in-channel vent visors, door sill protectors, Autocraft Platinum AGM battery.
    I've got a '10 Tacoma reg cab 4X4 4cyl man trans with AC. Every time I start to engage the AC there is a loud grinding noise from under the hood, sounds like the AC compressor starting to rotate. Noise only lasts a second then stops but it's quite loud, even shakes the truck slightly. AC works fine after that. Truck has 3700 miles on it. Obviously I'm gonna consult the dealer (reluctantly; I don't want them doing any other 'recall' work on it while it's there, such as trimming my gas pedal or floormats, etc) but I'm wondering if any other Taco owner have experienced this situation. If so, what was the diagnosis & fix? Thanks in advance. ;)

    Haven't heard of that before, but it sounds like the compressor bearings are bad. Dealer will probably replace it. Tell them to leave your gas pedal alone.

    My previous vehicle was like that when new. Eleven years and 180,000 miles and it never had a problem...just made a little crunch noise when the A/C engaged for the first time of the day.

    Mine just did this on Friday. I was leaving work and turned on the A/C. I heard that exact noise for about a second then it disappeared. No other strange noises, no problems with the A/C either from what I can tell. I tried it again to see if it would do it, but nothing. And no problems since. If it continues I'll take it in but till then not too worried about it.
