Replacing problematic relays

Just had the dying starter relay issue happen on a long distance trip in my wife's Giulia (~67000 miles). I was prepared for this and had bought a replacement relay from Alfissimo over a year ago to keep on hand... but that doesn't do you any good when you keep it in your nice warm well equiped home workshop 3 states away from where you currently are.

So I tracked down the NAPA AR6034 at a NAPA store in the eastern shore of Maryland on Sunday. I installed the NAPA relay on Monday morning. If you are willing to sacrifice comfort, skin and blood, then you can manage to get to the relay cover and relay through the narrow triangular opening in the engine bay. I'm a pretty decent sized guy, and I had 1/4" deep impressions, in addition to missing skin and blood, left in my forearms from squeezing both of my arms into that opening a good hour after I had completed the relay swap. I did end up having to pull the passenger wheel and partially undoing the inner fender liner, just enough to reach my hand in and pick up both the relay cover and relay that I dropped during my first attempt at cover removal and relay insertion.

So NAPA AR6034 works fine, although I was a bit skeptical because no one has mentioned the amp rating on this relay and the box/relay also doesn't have it printed anywhere either. Two of the terminals on the NAPA unit were copper plated, so that's at least a good sign they didn't skimp on quality.

OE Alfa spare going into the glove box now, so it rides around with the car.

Has the NAPA AR6034 held up well?

Thanks!

I had the dreaded U1008-00 LIN serial line error and had my water pump relay replaced at the dealer with the new AR relay sometime in February. Now I just had the start up relay crap out on me and I replaced all the other 5 ones in the front with Stark ( https://www.autodoc.nl/stark/12746960 ) which have 3 year warranty. I've also ordered 6 more of the Meat & Doria ones ( https://www.autodoc.nl/meat-doria/8127026 ) to replace the 4 in the back and then keep 2 as spares in the car. What a relay mess.

Thanks again for this topic! Top!

When you say,... "updated Mopar Relay." Are you referring to part # 6106094AA?
If not, what is the MOPAR part number, please?

Does anyone know when the new part went into service? Wondering what build date after which an owner would have the new part from the factory. I have a '21.

Been lurking here too for some time.
Think we are all got the same issue's sooner or later.

Replaced all the 10 relays in my Giulia today.
Mine is 2.0t 200hp 2017-02

Was a bit confusing, didnt have the relay "tree" as posted here, but a relay box.
What i can find online is that the factory put a Stelvio relay box in my car 😁.

Not surprised, been doing Alfa's since the 75's i owned.

But it can be helpfull. Dont think im the only one.

Go back to page 1 of this thread. Several pictures and diagrams.

That box looks like it might keep things more secure if vibration or shaking is causing the original problems. But where did the fuses go? Maybe that is a european only fitment? It would also make it harder to swap just the starter relay if needed in a pinch.

It looks like there are R1 R2...R4 and A bank markings on the housing you can use for identification, but not the same labels we have seen in other diagrams. You might be able to figure out at least the horn, ASD, and starter positions by trial and error removing one at a time and observing the symptom. (crank, no crank, no horn...)

Fyi for folks with adaptive dampers.

Felt like my front end was getting super soft with more body roll (in D). Saw there’s a relay in the trunk box for the dampers and swapped out with a new one. Firm front end was back.

Really seemed like she was stuck in D “soft” mode prior.

No codes on the dash or MES before swapping. Some relays will log a “ground to short” (rear defrost, starter, blower…). Not sure if MES has an actuator to test the active damper soft mode switch, didn’t see one.

No. I believe the starter relay (Napa AR6034 replacement) just failed again last night. Installed Napa AR6034 in Nov 2022 at 67059 miles. No start / no crank at all last night at 75xxx miles. It was pretty cold yesterday, below freezing, so when my wife called I grabbed my jump pack and Alfa diagnostic kit (Laptop+MES) and headed over. I had replaced the battery with an Interstate AGM unit in Nov 2021 at 55033 miles, even though the original Varta battery was still OK at the time. So because of the order of events and the fact that my wife isn't using the Giulia as much now that she has a Stelvio QV too, I figured it was a dead battery esp with the cold temps. Jump pack did nothing to assist. MES scan then showed intermittent starter relay code. At that point, I just left the Giulia in the parking garage until I can track down another relay today.
