Weird vents problem

Psycrow · 4 Aug 2006 at 23:12

I just noticed the cabin air speed settings aren't all working. it has 5 settings 0-4. 0-2 are all the same, nothing comes out. 3 then comes out with the force that setting 3 should do, setting 4 also works as it should.
Car is a 2001 Honda Accord. Any ideas what could cause this and how to fix it?

Cabin air speed ? you make it sound like an aircraft! Sounds like the resistor that controls the fan current has gone open circuit or (less likely) the switch has contact problems on the two lower speeds.

It's a common problem on Mondeos, the Heater Resistor pack dies, and the fan only works on speed 4 (and sometimes 1).

Sputnik, I couldn't think of any other way to describe it so shhh

Ideas on how to fix it?

locate the resistor pack and check it using a multimeter?

Sounds like the resister pack problem to me, a fairly common problem and in part matches the symptoms you describe.

I've read loads of people on the Mondeo forums having this problem on older cars, and my partner's Corsa

() recently developed similar problems which were also cured with a new resistor pack.

Sounds like the same thing on a 306 aswell the only problem is that the resistor packs are quite pricey

Might can get one from the scrapyard cheap(er) tho

setting 1 doesnt work on my golf, only 2 and above. from what ive found out its a simple replacement switch job

Sounds about right with the heater resistor pack, the one in my MGF went and i only had 3 and 4 (one of the 3 "resistors" were broken), pulled out the pack and found out the values for the silly wound wire resistors they used and replaced them all with proper ceramic resistors of similar values and now all speeds work and it will last longer than the manufacturers version..plus it only cost £2.50 inc postage for the resistors

Sounds like a plan, will look into it and probably do the same.

I paid about £8 for mine from the Ford parts counter, no idea how expensive Honda are, but it shouldn't be too bad...

Any ideas where said resistor pack would be on an Accord?

Matt82 · 5 Aug 2006 at 16:40

on the golf it is actually part of the swtich (ie the switch with the 4 settings).

try and remove it and see if there are resistors behind it

Psycrow · 5 Aug 2006 at 16:42

Ok will go out with my hammer and chisel

NightShadow · 5 Aug 2006 at 17:06

on the MGF they are in the passenger footwell in the side of the actual heater blower thingy (getting technical here!). Had to remove the glovebox and various other bits to get there but was well worth it for the satisfaction afterwards. Maybe try a Honda messageboard and do a search to see if anyone else has done it? failing that would a Haynes manual have it in there?
