Chosen Solution
2000 Honda Accord 2.3L LX Sedan with 199,500 miles My Mode Control Motor is stuck on 1 mode, blowing on my face. When a different mode is selected, the motor makes a clicking sound. Here is a link to a video I created of what’s going on: https://photos.google.com/share/AF1QipNg… The following link does a great job explaining where the motor is located: https://www.youtube.com/watch?v=CjclEh9p… I removed and opened up the motor to clean the contacts and apply dielectric grease as shown in this video: https://www.youtube.com/watch?v=jWcWUlbk…
Does anyone have any guesses what could be causing this issue? Motor needs to be replaced? A door is stuck/jammed somewhere? I could not find ANY motor replacements from O’riellys, AutoZone, AdvancedAutoParts, RockAuto, or such. I found a motor from Honda, but it’s $205. However, Ebay has them used for $50.
Thank you in advance for any help! UPDATE: SOLVED: Replaced Ac Heater Control Module (Honda Part No.: 79600-S84-A01ZA) 5 years ago my Ac Heater Control Module went out. To fix this, I jumped the positive side of C1 to the input leg of the 78dl05: https://www.driveaccord.net/threads/heat… A couple days ago my Ac Heater Control Module went out again (no led’s would turn on, no response at all). The dealership wanted about $300 for the part. Ebay has them used for about $90. I checked my local pull-a-part and saw that 2 2000 Honda Accord’s had been brought in in the past couple weeks. After checking about 6 cars in the yard, I found a car that clearly didn’t have the original control module installed. The plastic was a bleach white compared to my original which was a discolored yellow. And it felt more sturdy. Best of all, pull-a-part charged me $17.61 for the part! Replacing the Ac Heater Control Module fixed my blend door issue and my Ac Heater Control Module issue for $17.61!
Hi @parker_ , Can’t see it to well but it appears that there has been (is still?) arcing, across some of the the contacts in the assembly. Are the contacts still as shown in the picture or clean as seen in the video you linked? If they are still as shown in the 2nd picture, the set of contacts (shown in the picture from the bottom of the picture up) have been “joined” together and they need to be carefully separated (metal fingernail file perhaps) and cleaned so that there is no connection between them (at the burnt end anyway) Also when finished cleaning them ensure that there is enough contact “pressure” by bending the contacts slightly upwards so that they will be exerting pressure on their mating contact when the cover is replaced, thereby ensuring a good connection Here’s an image to show where I mean.

You need to replace the mode control motor.
