car radio receives no fm signal

howardmarks

The am and long wave work fine. Have checked the connection points in the roof and back of radio and changed the aerial whip but nada.
It has worked once when up in certain parts of dublins southside up high. (the car, not me )
Possible causes? Its a factory fitted Head unit that needs facias and hazard switches to convert so a simple fix is the most desirable outcome before I think of stripping it out and replacing it. As a note its never worked in the past few years (except of course up high) but the cd changer has packed in and longwave radio has some funny crap that ain't my type of funny.

Possible solution? Any car radio experts on here/?

what kind of car? Corolla?

Sounds like you have a Nissan rad/cassette unit. If I am right then the tuner module will need to be replaced.

howardmarks

it is a nissan indeed. fairly integrated unit. Where and how do I go about changing the tuner module?? I'd love a radio again : )

if it onlt worked beside the transmitter then the ariel isnt connected
it might look like it is have yoy checked the circut from the base of the ariel on the car body to the bit where it connects to the radio

thought i'd jump on the back of this query - i have a citroen c3 - the cd works perfects but there is dreadful interference on the radio and i can't listen to it. any suggestions greatly appreciated.

thanks.

Pull out stereo and check aerial connection in the back. Check connection in other end (antennae).

Done that. No difference. Whats a tuner module?

Anyone know where to get a cheap facia and hazzard switch for the the p11 144?

Duran, if the model no. written on top lid of your radio/cd is PU 2471 or numbers close to this then the tuner inside your radio needs to be replaced.
My full time job is the repair and decode of car audio systems so I know that my diagnosis of your fault is correct.

If the car is a Jap import, the FM spectrum used in Japan is different to here. In Europe, we use 87.5-108Mhz, whereas in Japan, they use 76-90Mhz. The implications of this is that Jap radios will only receive stations that broadcast beween 87.5-90, which in this country is usually RTE radio one.

Thanks very much for responding. How can I access the lid? Is there an easy way to pop out the stereo? Thanks again.

Ask your mechanic to remove the radio or buy special set of U clips in any motor factor shop for a couple of euro.

I'm having this problem with a Corolla Van, have you any info??

iamthemanwork

I would need to know the year of the van and the model no.of radio which usually starts with W and is written on front face.

Hey iamtheman

Sorry for delay, been on the road for last few days,

The van is an 06 and the radio is a W58814

Thanks for any info

In most cases with this model stereo the cause of poor reception is the areial.
I have not found any of these radios to have a fault. After replacing the complete aerial the problem was solved.

Thanks for the info, do I need to replace the wiring all the way back to the radio
Or just the aerial part that screws in?

iamthemanwork

You will need to replace the full length of cable. Advice first is to try your radio in another car or on a workbench so as to be certain as to where fault lies

Hey, the number is pu 2471A. R u based in Dublin? If u can't fix can u recommend someone, also an indiction of cost would be good. Thanks again.

iamthemanwork

Not Dublin based. This is a VERY expensive repair so my advice is to source a replacement in a scrap yard ---approx 50 euro. It will have to be vin coded to suit your car. You can get back to me again if you decide to go this route.
