First, I do apologize if there is another thread like this. I just don't know what controls this problem or how to search it in the case.

1987 RX7 N/A

My problem:
Example: If I push head and floor and does not change.

Things that do work:
You see with winter coming up I want my defroster to work for the windshield.

 

Use the advanced search feature and you'll find plenty to keep you busy reading. There are probably two possibilities to your problem. Either the logicon is the problem or the control device which opens/closes the proper air passage is stuck/not working.

 

I used that, but I have only come up with threads with: no heat, no A/C, No blower motor, No speed controll, and No Temp control. I want to find something on vent direction / Air direction.

 

Would it or could it be the mode actuator. I am also going to look at the logicon for my bad soder points.

 

Look in the FSM and focus on the "air control doors" as these dictate where the air flow is directed.

 

I believe the "mode control actuator" controls the "air control doors."

 

Not to tottally change the subject, but I just had my wipers and climate control not fuction for about 15 min. of my trip home from work. I did nothing to turn them back on. is there a common system that these are powered from or controlled from?

 

They stopped working and then all of sudden began working once again?

 

Yea, I don't really know why. Sound like a loose wire or ground somewhere, but I would think it would have to be a common system or something od that nature.

 

There's a plug w/5 grounds which fastens to a grounding block under the trailing coil and against the strut tower. There's a row of 3 wires and a row of two wires on top of that. One of those two wires is a common ground for the wipers and climate control.

 

Not to discount what satch has said, but you need to check the ignition switch. If you got the car fired up but the logicon isn't working, jiggle the key and i bet you it will come back on.

Airbags (vert) logicon, cruise control, defroster and wipers are on the ACC #1 circuit. The radio and headrest speakers (vert) are on the ACC #2 circuit. If the ignition switch is worn, the contact wipers in the switch will not engage ACC #1. Jiggling the key will usually solve the issue if it isn't too bad.

The cause of this problem is because of too much **** dangling from your keys making the start return spring in the ignition switch weak.

 

Aren't the wires coming from the ignition switch running to the fuse box IG1 (B/W wire), IG2 (B/R wire) and ACC (Blue wire) such that IG1 is for the turn signals, power windows, power steering, meter and engine fuses, IG2 is for the wipers, cooling fan and sunroof fuses while ACC is for the radio and cigarette lighter fuses.

 

I dont have alldata since it is my day off, but my memory says you are correct. I work in the 12v/automotive industry and have always labeled ACC as anything that is not powered during the start key position. The FSM and alldata might consider ign #2 an ignition wire, but I always call it an accessory since it is not true ignition.

 

So what should I be checking. I kind of feel lost

 

If you are referring to the grounding point you can clean the ground plug w/a liquid cleaner (quick drying electric cleaner) and then use some dielectric grease and press it into the plug, make sure the wires are firmly seated into the plug and sand down the grounding block.

 

I going to do that this weekend and report back.

 

I did not get to it this weekend. I well attempt for this weekend.
