My blower motor stays running when key is removed


That maybe do to the fact that it has a add-on thermal switch that is hot wired so that it will continue to run until it falls below a set temperature

Tuning problems


Hi, This sounds like an inshop repair. The technical term for the changer being set to 88.5 but works in 97.5 is "frequency drift" and could be rectified with the use of a calibrating instrument/frequency counter and an alignment tool assuming no component replacement required. Frequency drift can be caused by component failure, humidity, temperature etc.; The part "my car off the changer stays on" could be faulty trigger on inside the changer, faulty remote trigger on in your head/radio/controller unit. Good luck and hope this gives you a few ideas. Kind regards.

Unit will not stay on programed stations every time turn on have to set a station to listen to


Hi Jackie,

This is usually the result of connecting both ORANGE and RED 12VDC (+) wires to a "switched" source (meaning it is powered only when the ignition is in the on / run / accessory position).

The radio instructions specify the following connections:

Orange = +12V constant
Red = +12V switched
Black = ground
Blue/white = remote on
Green/Black = Left Front -
Green = Left Front +
Grey/Black = Right Front -
Grey = Right Front +
Black/White = Right Rear -
Grey/Red = Right Rear +
Black/Green = Left Rear -
Green/Red = Left Rear +

If you disconnect the ORANGE wire from whatever you have it currently connected to - and connect it directly to the battery's 12V (+) terminal (or other source that has 12V (+) with the key removed), your station memories will be retained.

Leave the RED wire where it is, so that the radio will shut off whenever the key is taken from the ignition - and you won't be stuck with a dead battery in the morning.

Good luck!

Only in certain areas and passing vehicals cause interferance


I'm assuming your using a RF unit (radio frequency). Whether this unit inserts in the antennea line or is simply broadcasting an FM signal via it's own antennea, it is still transmitting a low power FM signal. The idea here is to find an unused FM channel in your area, set your radio to that channel and program the Sony RF unit to use that channel. The signal the Sony RF unit is transmitting is low power due to FCC regulations and to minimize the possible interference you could cause to someone else's FM listening.

You are likely using an FM channel that is being overpowered by a real FM radio station. This is usually solveable if you only travel in your town by picking an empty FM channel. If you travel alot, the channel in your town that is empty may not be the case when you travel 50 miles away. That's just part of the problem inherent when using radio frequencies to get your music into your radio. You have to be willing to deal with it.

As far as passing vehicles, I'm going to assume that the vehicles that are interfering with your radio are doing the same thing you are doing, they are using FM radio frequencies to pump music into their radios and they are using an FM frequency close to or the same as the one you are using. Since having an unused channel on the FM band is pretty rare these days, if there is one, you can bet everyone is trying to use it for their own purposes since it is "quiet", until you come around!

If you can't put it back then the laser unit is no good anyway so it may be worth a try. I would not recomend super glue because it outgasses a substance that may cloud the lens. (that is how they use super glue to get finger prints from objects) Maybe use a thin film (very thin film) of rubber cement very carefully applied to the edge of the lens would do the trick. You must act fast because rubber cement cures so very fast. Another possible glue would be epoxy. It would give you a little more time before it starts to set up. Be sure you have the correct side up when you attach the lens, and be SURE that it is well seated in its socket so that you don't screw up the focus of the laser. Do a dry run or two with no glue to get the feel of what it takes. Don't forget to clean the "inside" side of the lens before you glue it in. You can clean the outside once it is glued in place. If all else fails you still are in a situation where you have to change out the laser assembly. Nothing ventured, nothing gained. Good luck.
