Question about Suzuki XL7
When i turn on the ac or heater past the lowest setting it makes a ruffling/whirring noise that gets louder as I move the settings up. It is still blowing but making the noise. Can you tell me what is causing this and how to access it to change it please?
Working in there is no easy task,
why not put pressure on all the HVAC parts in cab, one by one
as it makes noise, to see if the sound changes.
its the blower bad
or there is debris stuck in it.
or there is a loose part near by that vibrates in sympathy to the fan vib's , some times one can put a wedge in the parts casings and stop noise.
the HVAC is like 8 hour, in +out. horrid job. and lots of things can get busted doing it. collateral damage.
login to alldata.com
and read the FSM , chapter HVAC.

SOURCE: blower motor noise
the blower motor is like round cage and the only way to get to it is to take appart the dash. not the insterment cluster but the top and through the glove box is probably the only access. i doubt you will find a schematic just take lots of pictures while taking appart of what each screw looks like as it comes out. most the heater vents are in your way taking them out is not only screws but plastic barbs. just take every thing appart that is plastic and keep track of where it goes the cage you want is dead center of the dash. you dont need to take it out just get access to it. also what ever got there probably fell from one of the vents that blows onto the windshield so the top of dash removal may be easier if all you need is access to pull out some trash.

Remove the Glove box. You will then have access to the Blower unit. There are 3 screws that are holding the blow unit in place. You will need a Phillips screw driver and a 1/4 socket. Once you have located the unit remove the 3 screws and the unit will fall straight down. Unplug the wire harness and then reinsert the new Blower Motor. If you purchase an original GM part this makes life much easier, you just screw the 3 screws back into the holes and then plug the wire harness back in and reinstall the glove box. If you use an aftermaket part you will need to do some wire splicing to make it work but it is a 10 to 20 minute job depending on which part you decide to replace the Blower with.
