They are there. They are hard to get to. What is the complaint? Have you checked the fuse? Blower fuse (50 amp) under the hood.HTR-AC fuse (25 amp) in the instrument panel fuse box

I have a clicking sound under the glove box. When I put the control to the highest heat it stops. I am thinking it is some sort of relay switch. Anyone know what is over there?


behind the glove box is where your blower motor is located, it sounds like the fan may be broken or something may be lodged in the area causing the noise. i expect it is the fan itself, they have small clips on them for balancing and it may be loose, as the speed of the fan increases, force stops the clip from moving.

A loud rythmic clicking under the dash behind glove box when ignition turned on, once car has started, clicking is faster, but same loudness. Any ideas on the cause? Otherwise, the car rund great.


If I would have to guess, I would say it might be some debris in your blower motor. (usually located behind the glove box on a lot of vehicles). Try turning your heater fan off, or increase the speed, does the "clicking" stop or get faster? If so, you may just have some debris (leaf, twig, etc) in there. The problem may work itself out if thats the case.

2003 trailblazer I have no heat or air coming out of my dash vents


Is it no heat/air when sitting still, or no heat air period? If the heat and air blow slightly when driving you have a bad blower mower/resisitor and its not allowing the air to blow into the cab. If not blowing period when moving probably bad heater controls or fuse... Worst case scanario is you have an electrical problem that needs to be diagnosed

We have something lodged in the A/C blower fan. Where/how do I get to this fan to remove whatever has gotten in there? You can hear the fan clicking against something, and the noise increases in...


You can take blower motor out from pass. footwell area.
It's under dashboard , behind glove box , close to right corner. Three screw holding the assembly (I think it's three). From under dash it looks like round plate with screws at outer edge.

Hi i hear a ticking coming from behind the glove box, i tried turning every thing off, it still ticks till i turn the car off


It may be the heater blower fan. It is always on when the car is running. I'm pretty sure the blower is under/behind the glove box.
Does the ticking noise change when you speed-up or slow the fan speed? If so, there may be a leaf or something stuck in the fan blades. You might have to have the blower motor removed to get it cleaned out.
Hope this helps...

A/C BLOWER


most likely its the blower motor resister and is located behind the glove box. there are a few philips head screws you will need to remove inside the glove box and under the glove box to get the glove box out after that it should be a walk in the park

Honda Civic heater / blower noise.


you need to remove your glove box assy.(beleave only 2 screws and pivot clips) make sure its not anything from glove box that has slipped behind. once box is out uf way you can access easier the blower motor assy. it actually attaches into blower box from bottom side. when looking at you will find three screw/bolts fastening motor to casing. remove those and then slowly lower motor and fan cage(attached to motor shaft) out from housing. sometimes it takes a little convincing to come out but not real tough. once out you most likely find the object causing noise in fan cage or resting up on lip area of housing unit. once found install in reverse order. let me know if this helps or if we need to dig a little deeper into! good luck!
