New Here!
One owner 2011 Accent (253,000 miles!!!)
A/C Blower = no go on all 4 settings.
Motor is newer and does work when tested w/ power.
Resistor replaced w/ new.
Relay and fuse are good.
Looking to replace the whole unit. Dealer wants $500+

Want to try new switch unit unit ($50 online.)

Problem: can not remove the old unit. Get close with unit loose, however it only pulls out about 1 inch and can not get at harness connections in order to remove it.

Any step by step on removing and replacing this unit.

Thanks in advance.

Does your car have manual AC controls or auto (digital display)?
Sorry, I don't have step by step instructions because I've never had to removed the AC control panel on your model but generally manual AC controls control the flaps on the heater box via bowden cables. You need to disconnect the bowden cables from the heater box behind the dashboard before you can pull the control panel fully forward (or back, depending how you want to look at it).

Have you checked the blower motor power supply and ground? If the blower isn't working one of the two must be missing. Which one?

Manual unit with cable. Any tricks to removing the cable or simply where it gets disconnected? Buddy of mine quickly looked it over and determined it needed new switch unit. Local dealer here ($$$$) verbally confirms that the switches often go out. They were no help beyond that though.

The cables attach to the side of the heater box behind the center of the dash. If you look up behind the center of the dash from the brake pedal you should see the cables. On the end of the cable the cable inner is wound into a hoop which clips over a little plastic peg. There is a barb on the peg that stops the cable from slipping off. If you follow the cable back from the peg you should find the cable outer is secured to a clip. Unclip the outer then go back to the peg and press in the little barb then slip the hoop off the peg. It's a little difficult because you usually have to press the barb and slip the hoop off with one hand.

I've never done this job on your particular model. On the older Accent there were two cables on the same side of the heater box. There might be one on either side on your car.

I think I made that sound more complicated than it really is, so here is a video showing how to do it. It's the earlier (LC) Accent but I'm sure disconnecting the heater cables will be will be pretty similar to your model.

Any luck with the method autospark suggested above? My accent's fan/heater just stopped working and I'm thinking of removing the climate console to check if it's the wiring as well.

Before you go to all that trouble have you done the simple things, like check the two blower fuses?
Have you checked the power supply to the blower relay? A bypass test on the blower relay would be worth a try too.

Here are the instructions for the '08 model.. I have never done it.
Thanks, I saw those a few hours ago when I was digging up info prior to posting here. Panel looks nothing like that one on mine, and I don't see any indications of clips from the front. I saw a guy on youtube use some sort of miniature pry bar to take the panel off an 05 by going around the edges, but that looks even less like either of these.

Only checked the fuse box in the cabin. Didn't realize there was one in the engine compartment, like a total derp. Same with the relay. Thanks! Will check that tomorrow.

Whelp, it's not the fuses or the relay. Leaves the resistor (unless it would 100% work at fan speed 4, then it isn't that), blower motor, core, and console. The recycle air button lights up when pushed so it's either a few wires or just not that either.

Might have to take it in to the shop.

Speed 4 is straight 12v so the resistor is bypassed. I take it you do not have voltage at the blower motor or at the resistor? If the blower relay has power and is switching on when the key is on then it has to be the fan speed switch.

When the system is in OFF too the fan will not blow. Maybe the selector for mode is bad? A volt/ohm meter is the tool you need.

Cheers, didn't think of doing that! Tried removing the cable to test the voltage and well...I think I uh...might have a hunch what the problem is...
