Is this a relay?

Post by mbayrock » Sun Dec 03, 2017 2:47 pm

I found this under the dash near the steering column. I suspect it may be why my turn signals aren't working. But I'm not familiar with this.

If it is a relay, what should I replace it with?

Yes it is a relay. Per the wiring contact info in the picture, it is a single pole single throw relay, used to turn on a proposed high current load item/circuit by a low current supply control.
Replacement would be another same type relay with proper load ratings. NOTE it is not a flasher relay, but could control one.
Not knowing the application, am unable to say if it is your problem.

Do your brake lights work?

Do your 4way flashers all work?

It’s all down to two or three things with this vintage T Bird.

brake lights works
4 way flashers do not work
turn signals no longer work (fuse in glovebox seems intact)
The flasher and relay in the trunk have been replaced by a new solid state unit.

side notes;
Blower motor does not work
power windows do not work
clock does not work
Engine temp gauge does not work

I never had any of the other issues you reference so not sure they are related.

For assistance with diagnosing the issue with the signals try here - http://www.thuntek.net/cougars_unlimited/seqts.htm

More info here, including what Cougars has listed on eBay for '68's - http://stores.ebay.com/BARGANSPOT/1965- ... oting.html

That site linked above does reference a turn signal relay.

I'd recommend buying the cd's or books that reference your car to help with the issues. I bought a 69 specific cd rom off eBay and found it very useful. I also got a lot of help from the fine folks here!

I was eventually able to figure out that I needed to replace the column switch. That was after I replaced the trunk sequential unit...

I had signals and 4 ways but no brake lights anymore (they all had worked when I initially bought the car).

It took me a while to figure it out, and years to find a non tilt, non cruise control column switch (the 69 is not shared with any other Ford, nor any other year T Bird).
