Climate control buttons unresponsive. No tail lights. No speedometer. No tach.
 

So I bought this problematic SVX from Maryland and hauled it back to Ohio.

As the title says, my climate control buttons are lit up but do not even beep when i push them.

The speedometer and tachometer are completely unresponsive. Along with the gauge cluster lights are out. The fuel gauge and temperature gauge both work properly.

The tail lights do not come on when the head lights are turned on. However, the parking light button does power them up. The brake lights do work when the pedal is pressed.

There is no check engine light. There is not the common 16 power light blinks indicating a transmission problem. I have also checked every fuse, they are good.

So if anyone has had this issue or know what's going on please let me know. Thanks in advance.

Also, the front windshield wipers do not work but the rear one does work.

Do your sun visor lights work? How about the clock or cigarette lighter?

Frayed sun visor wires are notorious for shorting out and causing a multitude of problems.

Yes both visor lights work. The clock works. And the cigarette lighter works. I'm thinking maybe the PCM and the VSS. However, does the VSS kill the tach? Or would that be the PCM making it not work?

I had similar problems with a bad Timer Control Unit. This is on the same circuit as the visors, but it's harder to get to, so check the visor light plugs/wires first. I unplugged my Timer Control Unit connector and everything else started working. Of course, it could also be a number of different components on that circuit....

I think the visor wiring may have caused my Timer Control Unit to fail.

Good luck!

Thanks Ian. I'll definitely check that out. I haven't even ever heard of a Timer Control Unit. This is my 8th SVX. 🤬

Update:
So this morning I went out and took my glove box off, unplugged the Time Control Unit, tested my heater and air controls and there was no change.

However, my low beam headlights have worked this whole time. The guy I bought it from said they didn't work. I didn't check. :lol: Drivers side low beam bulb is blown.

Played with my drivers visor, noticed the light would go out. Found those dreaded frayed wires and disconnected them. Passenger looks alright and the light doesn't go out.

So that's as far as I've made it with that. Help please.

This is my thread from looking into a similar issue, while you have a different problem, the process for identifying it will probably be similar):

Basically I took everything off the effected circuit one by one until I found the thing that didn't work.

So my girl took the SVX on a joy ride in town to the car wash and the engine started to get hot. Turns out, both 25A fuses for both the fans were missing. Lol

On another note though, as I stated before, the Time Control Module made no difference when I unhooked it. However after putting it back in, I have the side door lights and overhead lights now. Still, nothing else has been remedied.

Also, this site won't let me upload photos using my mobile device. Is that possible or should I break out the old laptop?

One last thing for right now, that "binding" at low speed turns; is this normally in the rear differential or the front differential? Mine does it too. ☹

I would like to drive this car to Myrtle Beach, SC on July 4th so as much help, as quick as possible, will be greatly appreciated. Thanks

Mike

Binding is in the rear. Sometimes it is from sitting around too long and will fix itself with use. Lubegard transmission additive can help loosen up sticky components. Solenoid C is another culprit.
Take it to a parking lot and drive a bunch of slow speed figure 8's in both directions.
Also you could try putting the FWD fuse in and see if it stops. It's got it's own little holder up against the firewall on the passenger side.

Re: Climate control buttons unresponsive. No tail lights. No speedometer. No tach.
 

Blacky, when you say, "It's got it's own little holder up against the firewall on the passenger side." What is that in reference to exactly? Because as far as I know, the empty FWD fuse location was in the fuse box on the driver's side right behind the battery. Am I going crazy?

Also does anyone else have any input as to why my speedometer and tachometer do not work. How about why my climate control lights are all lit but do not do anything?

You are not crazy.
The fuse box behind the battery where the FWD slot is. Bottom right

Gotcha. Thanks. I'll try that fuse tomorrow before work and get back with you.

Re: Climate control buttons unresponsive. No tail lights. No speedometer. No tach.
 

Oooops! Sorry I was thinking of another Subaru. Our '97 Outback has the fuse in it's own holder.

Re: Climate control buttons unresponsive. No tail lights. No speedometer. No tach.
 

😀 LOL it happens to the best of us sometimes.

Re: Climate control buttons unresponsive. No tail lights. No speedometer. No tach.
 

So I put the FWD fuse in the car and there was not a FWD indicator light. Anyone?

I haven't drove it yet although I did put it in reverse and drive.

UPDATE: found the FWD light.
