Heater/AC blower running on highest speed only

I need some help:

My heater/AC Fan blower does not work at the speed of 1,2,3 and it starts at the speed of 4. Sometimes it gets a little too much of heat an d I am sure too much AC in summer.

can anyone show me/advise me how to repair it or what could be the problem?

Can I fix it myself? N e online articles?

Thanks

Sounds like you need a need selector switch. On my 01'. the the gray facia plate around those controls has a few screws. Remove the facia and there are screws to remove the climate control center. From there I'm sure it's only a matter of switching out the old one for a new one.

Bzzt! Wrong. He needs a new blower resistor.

Part number 27150-8B700, should run about $20. Pic of location:

Thanks Brent. I'll keep this one. Sounds like it happens often.

Can any one suggest me a good web site, where I can buy this part. Nearby local dealer does not have this in stock neither another well known store.

Thanks.

If the dealer doesn't have it in stock, order it, they'll have it in 2-3 days tops unless it's back-ordered. Ordering online will take just as long, if not longer, and cost more after shipping.

It worked like a champ. Installation was very easy. Now enjoying all FAN..:)

I also have this problem today...AutoZone has it listed in the store computer; but not online...Dealer has to order it...

Six of one...half a dozen of the other... :rolleyes:

I can get to mine without removing anything...Have it in front of me, in fact...

Grungy lookin' mofo...the salt in the Winter air, I guess... :(

I was finally able to upload this composite photo today... :D

Edit: or maybe not...now it tells me the URL does not exist... :rolleyes:

Let's try this again...

It shows the new [smaller] resistor at the top; the AutoZone [Wells] box & number in the middle; and the Nissan box/number at the bottom...

If you notice, the number on the actual resistor [that one is the AutoZone part] is the same as the Nissan part...In fact, the two resistors [AutoZone & Nissan] are identical...and within a dollar of each other in price...

I suppose they are both made by the same company...I just find it odd that the dealer and an aftermarket retailer both buy from the same mfg [with different packaging]...

I ordered mine online today from xterraparts.com:

Lil cheaper than Autozone, but with shipping came out to about 26 bucks.

Well, this resistor lasted about 5 years...Not too bad...It just went Tango Uniform last week... :uhoh:

Same as before...all grunged up...had speeds 3 & 4 left this time...

Brent's location pic doesn't seem to show up...My resistor (in an 02 Xterra) is on the passenger firewall, where it meets the floor...Two Phillips screws holding it in, after pulling the connector out...

Back in working order again! :wink:

Fan works on 4, and intermittantly on 2. Got a resistor from Autozone, put it in, no difference. Would the fan speed switch be the next thing, or could it be a defective new resistor? Other than the resistor, is there another part that is a common failure? I'm a Honda Tech, which is an entirely different species!
