SLICK 2.2 Posted November 22, 2007 Share Posted November 22, 2007 I tried searching with no luck. I have a 95 accord. The problem is when i turn on the fan it only comes out of the dash vents and nowhere else, does not mater what you select on the knob. Happens with both the a/c and heater. Any ideas, i checked all vaccum hoses and they are fine. Link to comment Share on other sites More sharing options...
Ben. Posted November 22, 2007 Share Posted November 22, 2007 You check the vacuum hoses inside the dash and all? Link to comment Share on other sites More sharing options...
James Matteu Posted November 23, 2007 Share Posted November 23, 2007 Frankly, I am surprised by the last reply. I thought only American cars use vacuum lines to actuate the vent positions inside the car, but I do know Honda never has. Anyways… SLICK 2.2, for some reason, either your Mode Control Motor is not getting voltage, or it is and is not responding properly. First, check your #15*, #18, and #08 fuses. *You may not have a #15 fuse. Then you want to make sure the Mode Control Switch Assembly is working properly, c.f. #16 below. Check the function of the Switch: Light Green/Red = Mode Control Motor Ground Light Green/White = Vent Light Green/Black = Heat/Vent Blue = Defrost Blue/Red = Heat/Defrost Yellow/Green = Heat Then you want to make sure the Mode Control Motor (P/N 79140-SV4-A01) is working properly, c.f. #07 below. Check the function of the Motor, below is taken from Honda P/N 61SV405: The terminals are numbered 1-7 from left to right with the pigtail lock at the top. 1. Connect battery power to the No. 1 terminal, and ground the No. 7 terminal. Caution: Never connect the battery in the opposite direction. 2. Using a jumper wire, connect the No. 7 terminal individually to the No. 2, 3, 4, 5 and 6 terminals in that order. Each time the connection is made; the mode control motor should run smoothly and stop. Note: If the mode control motor does not run when jumping the first terminal, jump that terminal again after jumping the other terminals. The mode control motor is normal if it runs when jumping the first terminal again. 3. If the mode control motor does not run in step 2, remove it and check the mode control linkage and doors for smooth movement. If the mode control linkage and doors move smoothly, replace the mode control motor. Link to comment Share on other sites More sharing options...
James Matteu Posted November 23, 2007 Share Posted November 23, 2007 My bet is on the Motor itself. You do of course want to make sure you have a proper ground to the chassis. Check everything before you throw money and parts at the problem. Link to comment Share on other sites More sharing options...
