My Air conditioner in my 1998 HOnda accord is not blowing through the middle vents.It is coming out where the defrost is.I have it on the correct button to blow out of the front vents...but it's like it's still blowing out by the windshield.. Anyone encounter this problem?.

 

Sounds like a bad actuator ..... but this is a question for deserthonda!!!! oh yeah .... DH, this one is air!!! LOL

 

How much does actuator cost?

 

Disconnect Mode Control Motor. Jumper a fused power wire to mode control motor terminal #2. Jumper a ground to mode control motor terminal #1.

Motor should cycle and stop at vent mode. Disconnect jumpers after motor has stopped, IMMEDIATELY. Reverse jumper connections, swap #1 to #2 and #2 to #1 (reverse power and ground). Motor should cycle and stop at defrost mode. Disconnect jumpers after motor has stopped, IMMEDIATELY.

If mode control motor does not run when jumping terminal #1, jump terminal #1 again after jumping all others. Mode control motor is ok if it runs after jumping terminal #1 again.

Use a multimeter to check for continuity between terminal #7 and teminals #3, 4, 5, and 6 while manually cycling motor between vent and defrost. Continuity should be indicated on each terminal momentarily while motor is cycling.

With the locking tab facing up, terminal #1 is on the far left and termainal #7 is on the far right. See colors below for orientation.

The mode control motor is completely controlled by the AC Control Head

AC Control Head 20 pin connector = Mode Control Motor 7 pin
5 = 1 BLU/BLK
6 = 2 BLU/WHT
11 = 7 YEL/GRN
17 = 3 BLU/GRN
18 = 4 LT GRN/BLK
19 = 5 GRN/YEL
20 = 6 GRN/BLK

This is for Auto AC, thought I would get ahead in case yours was auto. The mode control motor should be down on the left side of the heater box, center console, near your feet. 7 pin connector.

If this is not correct, then let me know.

 

it looks like 2point has your diagnostics covered ....... I'd never have come up with that btw. For parts pricing, the site of choice here is Majestic Honda...... you should be able to look up parts there.

 

I am working on a huge AC project dealing with diagnosing Honda AC systems. If you have a digital camera and can post pic or send me pics, it would be a huge benifit to me and all folks I help in the future with a similar problem.

Bottom pic style is mainly what I am looking for and anything else that you may play with fitting the style of the other pics too please.
