Where is the Accutech Compass Prob Located On My 2004 Itasca Horizon

My Accutech Compass is reading about 90 off. I called Accutech and they said I should find the prob to make sure it did not loose a mounting screw, but they could tell me where to look for the sending unit/probe. All they could advise me to do is to follow he probe wire.

I did that as best I could and then the wire disappeared in behind the firewall and I could find the other end where. I looked from the outside too.

Note: I also confirmed the unit would calibrate.

Can you tell me where to find this Accutech compass probe on my rig?

Thank you!

With your help I was able to locate the compass sensor in the storage cabinet above the driver's seat. (See picture.) And after I removed the odd shaped 10" odd shape, vinyl cover... the 3-wire compass sensor just laying inside... and you can see in the picture a mounting tap was broke off.

Then I remembered Winnebago took off the front cap when they replaced my roof last year, which now that I think about corresponds the time I first noticed the problem.

...So I'm not happy to add this compass problem to the other electrical problems Winnebago techs created after they replace my RV roof. (I had some wind damage and fortunately The Hartford insurance company covered the $35K+ cost to repair.)

That said, if you ever have Winnebago take off your front cap, you might want to make sure your compass works; and your Traveler Antenna hunts and locks on the satellite like it should before you drive off.

And if you have Winnebago take off your rear cap, you should also check to make sure they hooked up your tow lights.

In my case, Winnebago released the coach to me after they competed the roof repairs: ...and when I tested my Satellite Dish (before I left their facility in Forest City) it did NOT work. So that was a 3 hour delay to get it fixed right. But at least I caught it before I left their facility.

Unfortunately, when I hit the road, about 200 miles away, when night came, I noticed my tow car lights were not working.

What happened was this: When the Winne techs took off the rear cap they forgot to plug in the tow light 7-pin connector and it was just tied up and out of the way. (Don't you just hate dealing with issues on the road!)

And now 1 year later, when I took the time to find out why my compass showing 90 degree off at all times: today I found the compass sensor was just siting in a pile of wires, because the Winne techs did not hook the compass sensor back up when they pulled the off the front cap.

No worries... I like fixing things and when I remounted the sensor my compass works great again!

This compass fix is not a huge deal, but it does bring up another matter since I would like to think the Winnebago Service facility in Forest City is the "gold standard" for coach repairs.

Plus, if you ever go to Winnebago you will see (every day) a large group of proud Winnebago owners, just waiting to hand over their money so they can drive off with pride. So yes, Winnebago is special for some reason? And I don't feel that way when I have my engine serviced by Cummins.

Winnebago... Are you listening? Your service model is amazing and so are your customer service people, the front desk scheduling, and in your parts department, but something is not right in the back room! (minor maybe, may not?)

I think it's possible your managers are pushing your techs to hard to meet management's "time/service quality/profit goals," because your techs are making a lot of mistakes. Therefore, I have to conclude they are being rushed.

For another example: Just last month, I took my coach to Winnebago for a $350 pantry side repair (and about $800 of other work), but I left very unhappy with the pantry fix. ...So much so I ended up redoing the pantry slide repair myself when I reached my camp spot in Montana. And I wrote a thread about the right way to do a pantry repair for other owners to follow.

So I wrote my Winnebago service manager about this matter; and he refund all the labor on this job except 1/2 hour. As to why he did not refund 100% I don't know? I'm guessing Winnebago is all about margin and profit these days.

They still charged me $100 for the slide part, which is basically only slightly different than the $20 slide you can get at Home Depot. (But I accept some parts are reasonably priced out of Winnebago and some are not, and I don't mind paying for convenience.)

...But today, when I learned the Winne techs did not mount the compass sensor back in the right position, after they took off the front cap last year, I find it frustrating that my trust in Winnebago service is being challenged. ...And so I'm singing my song again: Winnebago Are You Listening?

Replaced our Pantry slide tracks last year after the little lock tab broke. $110 for a $20 part. Took my wife and I an hour to replace on our 2004 Itasca Horizon 40AD. Also looking for the dash Compass/Temp display that has a shorted circuit board. Always something

Sorry for the late reply.

Here's a link to buy a new one on Amazon:

...but I'm sure you can call a junk yard and they will ship you one for much less. Maybe not? I'm amazed at what junk yards charge sometimes.

==> Please let us know where the temperature probe is located.
