Vent/AC not blowing...
Hi all. Okay, I mentioned this a couple of months ago but it stopped happening until now. It appears that the fan is blowing a tiny little bit. It seems the defogger works alright but very, very little air comes out of the vents.. This problem was intermittant but I think it's permanent now.. Does this sound like what a blower-motor does? If I put the fan level on 4, I feel a little bit out of the vents. Otherwise, I feel nothing...

Okay, I just talked with someone and they say it sounds like the head-unit (climate control) needs to be replaced.. I'll find out for sure tomorrow...

Re: Vent/AC not blowing... (Sal Collaziano)
Hook power from your battery to your blower motor. If your blower motor runs on high, it is the resistor in the fan selector. If that is the case, then you will need to replace the a/c control unit as I don't think the resistor is replaceable by itself. If your fan motor does not run when you hook 12 volts to it, then it is the fan motor. This is a common problem with aging Hondas (I used to be a service advisor for Honda). I have also seen this problem on all other makes as well, when I worked for Discount Auto Parts (Advanced Auto Parts now, as a store manager.) Hope this helps you out some.

Sal, on my 96 I notice that the vent air doesn't always blow very hard (I mean very little) when turned on and then after a while it blows fine. Not sure what the problem is, but I do notice that even when it is not blowing out of the vents it is blowing out of the floor area... :confused:

Replace the blower, its chaep easy and probably overdue. Mine was shutting down now and then so I changed it. After, the air movement was easily 3x what it had been before I even realized it was a problem. I paid like $25 for the motor without impeller and it took 45 minutes to replace.

Re: Vent/AC not blowing... (redvette1986)
Thanks all.. I wound up leaving my car with my mechanic this morning - so let's see what they say. The problem Denny is having is the way mine started out.. I don't think it'll last too long that way... It was off and on for me for awhile - but in the dead of Summer it just stopped working altogether...

Re: Vent/AC not blowing... (Denney)
Hi Sal, I see you have an 87. Looks like we are both having similar problems but your's may be fixed before mine. My new blower motor arrived today, it may take a day or two before I fit it.
Other reasons for no air pressure can be a blocked evaporator. Or of course loose ducting or airleaks etc behind dash.
My fan was stuck on one speed, it wasn't the climate control it was a 5 AMP FUSE on the firewall.
I've had my climate control to bits, including removing the melted plastic pins and cleaning the pad contacts, using the tech tips and other help.
I'll be very interested to see if your new blower fixes the problem -I'm personally not too hopeful on mine.
The guru of Aircon is SunCR - hope he will chip in if you have further problems.
good luck

If you only have air coming from the floor vents, the 1st place that I
would check is the vacuum hos coming from the manifold to the inside of
the car thru' the firewall. What you will be looking for is a (i
think) 3/16ths vac line with a small cannister that looks like a cone with
vac lines coming off. On the big end there are 2 lines - 1 goes to the
passenger compartment, and the other goes to the vac reservoir (usually
a globe - left front engine bay, On the little end (point), the line
goes to the manifold. The cannister is a check valve to maintain vacuum
to the system when you have the heavy foot. When you only have floor
air, there is usually no vacuum. Sometimes the vacuum hoses will
collapse or just desentigrate from heat and age. If this is good, then go
check the dash control. Hope this helps.
