    Well I searched for a good hour or so and couldnt find anything on this topic, so I thought I would ask and see if anyone has had this problem. Sorry for the long post

    Starting today, my air conditiong including my heat and fan stopped working in my 2006 DC Sport. I ran a morning errand...and I had nothing. The truck started fine like usual, just no a/c, heat, and it wasnt even blowing hot air. Well later in the day ( after the truck had sat for a couple of hours) I get in to go to work, and everything works like normal, including the a/c, heat, and fan. Well after work I go to leave, the trucks starts but nothing works again. So now I am home trying to figure out what is going on.

    --I have tried checking all the conections, fuses, etc. And i have put all the a/c controls in various positions. If anyone can help I would greatly appreciate it! Especially since we have 110+ degree tempatures heading our way soon here in AZ. :p

    Sounds like the blower motor might be going out on you. I'd say it was a short but 95% of the time that would blow a fuse. I know if you take the motor out autozone or pepboys used to check them for free if you don't know how to yourself.

    When the problem happens, check for 12v at the blower. If 12v and blower not running=bad blower. Much easier to find without taking the blower out.

    do a search on here for the blower motor resistor. could just be connection problem. mine wasn't blowing anything except on the highest setting. it's a common problem. unplugged, cleaned, replugged, fixed.

    He said it's not working at all=blower, not resistor.

    I have the same issue. It has happened to me for the past 3 years now, only during the summer though. I thought I would replace the blower as that is the issue (I checked to make sure all connections are tight and nothing is melted either) but I just keep giving it a good smack and it turns right back on every single time so why spend the money until the smack doesn't work anymore right? It's on the pass side under the glovebox. There is an aftermarket one avail for around $100.

    Well just an update, it didnt work when I first went to drive the truck yesterday morning, so I tried the classic 'hit the dash' method and it turned right on and hasnt done it since. Not sure if this means a loose connection, or something else, but for now im content that it is working:)

    we're a few months into owning an 05 tacoma sr5 trd and are experiencing a similar problem.

    problem: the fan doesn't blow but the AC is clearly operating / engaged, same with AC turned off but fan on for defrost etc. Sometimes the fan works and sometimes it does not. Once we went over a bump and the fan kicked back on -- which makes me think it's a connection issue.

    Any recommendations for manuals which are going to show me where to look / schematics (haynes / chilton or ?). This is my first toyota so it's all new under the hood to me.

    thanks.

    Bad spot in the fan motor probably. You'll need a new one eventually. Bang method will work for awhile.

    I have the same problem and it just started last week. After some research on here I decided to order a new motor from rockauto. From my research it was mentioned that this may be caused by not changing the cabin air filter enough. I just went ahead and ordered a couple of replacement filters also. Shipped for everything was around 50 to 60 bucks and should be here tomorrow.

    rockauto also has a discount code listed somewhere on this site. I think it was 5 or 10 perecent off. Compare those prices to Toyota who thinks there motor is worth 200 and an filter is 30. Autozone was 110 motor and 27 filter

    I have an intermittant connector issue. Wiggle a wire and the low speeds kick in. Never a problem on high. This means it's the resistor connector.

    make sure the cabin air filter is changed often if not it could lead to the fan not spinning. i stuck my hand in there and gave a little spin with my fingers and it started spinning fine. im sure if you could figure how to remove the fan and clean it out it would save you some money.
