Update: Electrical interference in the AM radio - 2005 Elantra

Hi all,
Just wanted to let the group know that Hyundai has fixed this problem. Don't expect the dealer to volunteer details on this...according to my
work order, the parts alone were listed in excess of $1,000.00. The dash controller and the cruise control were replaced, so the labor is rather extensive as well. Maybe hyundaitech can add more about the official status of this repair. Mine was covered, hope that yours will be too.
My list of problems, current and fixed, at only 7000 miles, 2005 Elantra:
1. AM radio virtually useless - fixed (see above). 2. Air conditioning non-functional - compressor replaced. 3. Intermittent shift problems, auto transmission, 1st to 2nd gear - Hyundai won't even look at this, for reasons that totally elude me. 4. Heater/defroster motor extremely noisy - need to get this in to the shop. 5. Brakes moan on release, intermittent. Sounds like no anti-rattle paste? - need to get this in to the shop. 6. Safety recall - to be scheduled.
At this rate, the car will be almost completely rebuilt by 60,000 miles.
Cheers

That's interesting! Is there a TSB associated with this?

I find no TSB on this issue. I'm interested in knowing exactly what was done. So, for example, what is the dash controller to which you refer? I presume replacing the "cruise control" means they replaced the underhood computer/actuator unit.
I also find it very odd that they won't look into your transmission complaint. I hope this doesn't mean you take it in and they tell you that they won't look at your car. I wouldn't be terribly surprised if it means they checked and road tested it and everything seemed normal, considering that it's an intermittent problem.
For your blower motor, you may want to pull it out and have a peek inside. In most cases leaves or other tree droppings get inside the fan, making noise. This isn't covered by your warranty (since it's not a defect), so the dealer will want to charge you unless they feel nice enough to try to slip it under Hyundai's warranty radar.

I wonder if he means the ECU? That's a likely source of RFI.

That would also make sense, since it generated RFI when it's engaged.

I had this problem with an Excel. There were "helicopter" seeds in the blower.

If the car doesn't have one already, install a cabin air filter. IIRC, the filter sits between the exteriour air inlets and the blower, so it will stop any debris from getting to the blower.

Shouldn't my Elantra have one in place? I haven't asked for its removal and at 7000 miles, it shouldn't have disintegrated yet. Under these conditions, should I still R and R the blower motor?
Cheers

Sorry I missed this post earlier. While Elantras were all equipped with a spot for the filter, not all were equipped with the filter. It's a narrow enough opening that you probably can't get your hand in very well. You could always try getting a filter to put in and seeing whether you can pull anything out when you do that. You'll need to remove the glove box and a bracket to get to the filter opening.

If you don't feel like paying for Hyundai's overpriced filter, I have a DIY for making your own that uses inexpensive air conditioning filter material on the Elantra Club web site.

Please do give me additional details about the repairs for the AM if you can. I'm very interested.

For those interested, here's what the repair order says:

Anyone that can supply a servicewriter to english transation, please jump in.
I had to wait about 6 weeks for this stuff to come over from Korea. The service manager heard about this repair at a service seminar of some type. He said that I had the first of the new parts in the US.
ANYONE who has the symptoms I described in my earlier postings (April timeframe) should consider looking in to this matter for the reasons I described previously. I do not take EMI that is this servere lightly.
On the matter of the transmission problem... The first trip in to the dealer, I had a service tech ride in the car and he experienced what I complained of and agreed that the operation of the transmission wasn't correct. When I presented the car for the AC outage, I requested that the transmission complaint be listed again as I didn't want the lack of a complaint to be construed as acceptance of the situation on my part. The service writer would not list the transmission problem on the service record. The service manager did take a 10 minute test drive during which the problem didn't happen. The New York State lemon law states that refusal to service is an automatic trigger for the lemon law process, so I went that route, since Hyundai wouldn't provide an alternative. The BBB AutoLine folks negotiated a settlement with Hyundai, and then Hyundai failed to meet the terms of the agreement. As matter of fact, Hyundai completely ignored the agreement and returned to their previous position. This was to have gone to arbitration, but AutoLine could only perform arbitration while I was away on travel, so now I will be going through the whole process again.
Hyundaitech, can you post a description of blower motor R and R?
Cheers all

Thanks, JCW. They've replaced your cluster (speedo/tach/gauge/indicator) assembly and your cruise control actuator/computer assembly. I presume your odometer started again at zero.
Since you seem to have a BBB case open, I presume Hyundai has received official word that you have an issue that the dealer refuses to list on their repair order. I'd think about writing it on the order myself next time I have the vehicle service, since I really am that large an arse.
There are three screws holding the blower assembly in the bottom of the heater case. You'll need to remove them and move some wiring out of the way (perhaps unscrew a retainer and unplug a couple items). Then pull the blower out the bottom. I don't recall how easily it drops out on this particular car. On some cars, it's necessary to pull the carpet back and then cut the padding and temporarily move it to the side to get enough room to drop the blower. If you have to do this, just put the padding back and place the carpet back in place when done. The alternative is to pull the dash and the heater box to get more room.
