Default Air Conditioner/Heater Dial Broken on 2005 Rio

The dial works on the lowest setting but any time I try and turn it up, the air conditioning or heating is non-responsive. I can push the dial in like a button and it will work for the duration of the time I'm holding it but then turn off immediately after. I'd rather avoid taking it to the dealer if possible. Can anybody help me out?

look in the back. I bet its loose. Mine did the same thing because somehow, it heated up some much in the back that the part that holds the plug in melted a little bit causing the control to short out. I had to push mine in and it would start working again. simple fix = zip ties. I took a zip-tie and made a loop then put it through the wires of the plug and at each end, i used the loop the was created when the original loop was pinched and ran one more on each side around the unit and put the panel back in place. However, you will have to move the zip ties that are wrapped around the unit and and spread them apart a little bit so the panel will clear and to prevent them from covering the 3 buttons at the bottom.

never under estimate the power of my RIO:cool:

Default 2004 Kia Rio - Same Issue

I have the exact same problem with our 2004 Kia Rio. I've done some cross-referencing and it looks like 2003-2005 had the same heater control, so I figured I'd post in this thread instead of starting a new one.

About a week ago the blower fan speed control switch in our '04 Rio stopped functioning properly. I originally thought it was the blower motor resistor (had the same problem on my '03 Blazer), but I am now convinced the problem is with the heater control itself. As the OP describes, ours only works on '1' and not any other setting. Holding the switch in like a button does indeed start the heater again, which turns off the moment pressure is released from the switch.

I removed the bezel and the four screws holding the heater control, and I noticed if I had the heater control hanging loose, it would function normally. When put back into place, it would stop working. I grabbed some electrical tape and wrapped it once around the wire/plug leading into the speed control switch. Then I pulled it taut and secured it tightly, and for a day or two this worked nicely.

Unfortunately it seems to get quite warm inside the cavity behind the heater control, causing the electrical tape to melt and let go of the wire. Based on how warm it gets in there, I'm not too comfortable with the zip tie solution suggested above. After two failed attempts, in vain we tried taping the switch from the front with a taut piece of electrical tape. This only seems to work for about 15 minutes or so before the tape gives out.

Now, the heater switch is to the point where it requires a significant amount of pressure to activate the heater. It also no longer works on '1', it simply doesn't work unless pressure is applied. I'm getting worried that continued use in this state will degrade the switch to the point of no longer working -- horrible timing to happen in the middle of winter!

I've managed to locate a salvage heater control. My question is, can anyone outline the procedures involved in removing and replacing the heater control switch? The bezel and four screws are simple, and the plug leading to the speed control switch seems easy enough to remove. Other than that I'm stumped. I just can't figure out how to disconnect the vent and temperature controls which are connected via pull-cables instead of wires. I checked the shop manual and couldn't find the info I'm looking for. A description on how to remove and replace the switch would be excellent; with pictures would be a godsend.

Sorry for rambling, I just wanted to ensure I got all the details across. I'm a pretty technical and hands-on guy, and if possible I'd like to install the new heater control myself instead of paying someone to do it.

Just save yourself some time and do the zip-tie method, it works. I did it maybe 1 year ago and it still have not givin me any problems at all I wouldnt suggest it if it didnt work. It works on all speed and the knobs are functioning properly.

I would do this if my knob for selecting the way air comes out of the vents (position selector) didn't brake off, so now I only have the option of using pliers to change position of the knob.

Can anyone outline the procedure for taking off that wire that is connected in the back that is very hard to get off, like kiaowner2004 asked for, so I can replace the whole unit please!?

Stick your head under the steering wheel where there pedals are and look up to the right hand side. You will see a white disk with the wire attached to it. Pinch the white plastic piece with your fingers and the wire should pop off. Go to the passengers side and there is a panel in the way. Pop the two plastic screws pulling from the middle of the plastic screws so they pop out. Once removed. pry the panel back and there will be two more behind it. Pop those out and pull the panel off. You should have access to the other wheel and remove the wire the same as the first one.

You shouldn't need to replace the whole unit. You can actually buy the swtich from the dealership. Might be cheaper than buying a complete unit.

I did this but put a zip tie around the inside bezel with 2 zip ties already made into small loops on it tightened it really tight around the bezel by grabbing the end with needle nose pliers and rolling twisting them till zip line was really tight the bezel or back of the faceplate had flared out a little. Then the two loops keep to the side when tightening put two more zip lines through wires at back of plug and tighten down on each side . It worked use good 8" heavy zip lines and it doesn't show from the front . Ps had to pull radio to get room to do this . Good Luck
