No high speed on AC blower but slow and med works and theres cold air. Can this be the same transister under passebger dash?
There should be a high speed blower relay that bypasses the resistor for slower speeds.
Check with an auto parts store or the dealer.

Usually when the blower fan only operates on hi speed, its because of a failed blower motor resistor. You still have hi speed because on hi, the power going to the blower motor goes directly to it, as opposed to the lower speeds, when the power is routed through the resistor, thus lowering the voltage, which in turn lowers the speed of the fan. The resistor is usually located near the blower motor itself, under the hood back near the firewall.

If the fan only works on high speed I'd suspect a bad resistor in the fan circuit. On a new car it may be called by a different name but in essence does the same thing. It steps voltage down to the fan motor in all speeds but high. I'd check that first assuming there is no obstruction interfering with fan operation in all speeds but high overcomes that obstuction. I've seen mice among other things in a fan box on many occasions. I think the A/C problem is unrelated to your fan problem. This one may be a little harder to solve. The first thing to check is Freon level. The compressor won't cycle if the freon is low to avoid damage to the compressor. Do the fans, both under the hood come on when you turn on the A/C? If so it is more than likely just a Freon issue. If not take it to your local Honda Dealer.

You probably hit one of the veins on the squirrel cage, mounted on the fan motor. You might be able to take the fan out and straighten these, to get the vibration out, if not you'll have to replace the whole fan. Good luck. I hope you can straighten it and don't have to replace.

This will be 2 separate problems.
The blower motor operating only on high speed can be fixed by replacing the blower motor resistor.
There are several reasons why your A/C is not getting cold. The most probable cause is that there is a leak in the system and the freon has leaked out. The size of the leak and where it is leaking from can vary immensely, as will the cost of repair. You might get away with just a recharge for a while, but that will not FIX the problem...it will definately do it again if the problem is not repaired properly. A small leak, costing $150 to repair right now, could easily end up costing $1500 or more if not fixed properly.

most likely is has leaves or other debris in the fan. take it down and clean it3/4 screws and its out. just above passengers feet. you also need to replace the cabin filter. the glove box will need to come down/out to replace the filter.
