Hi S, It seems to me that the surge may have been caused by the alternator before blowing. A short circuit may has caused the diodes to blow, which in turn will probably have been caused by a short circuit created when the radio theft took place. The first thing to do is isolate all loose cables and make sure that there are no internal shorts inside any auxiliary equipment. After making repairs to the alternator, or fitting a replacement, disconnect all connectors to switches and other controlled units such as cabin heating and ventilation systems, music, TV and navigation systems. The fuse box is located in the engine compartment. Check all for continuity and replace burned fuses and at the same time, check for any damaged relays. Once are you satisfied everything is as it should be turn the ignition key to auxiliary and check all cables for overheating. Connect each unit one at a time until a fuse blows or all are connected. If a fuse blows while connecting, replace the fuse, but leave that circuit disconnected and continue until all are connected or another fuse blows. Once the dangerous circuits have been identified, trace the fault either into the wiring harness or the units. Repair if possible or replace. Once that has been done, crank and start the engine. Check all circuits with the engine running and the park brake fully engaged. If the engine fails to start check the electrics which operate the starter motor. Hope this info is at least a little helpful. Regards John

SOURCE: radio and all dome lights are not working.

interior fuse should be the culprit. Look for the Radio fuse inside (normally 10A red) sometimes labeled CABIN on the fuse layout

2000 MONTE CARLO BLINKERS DO NT WORK,AC/AND HEAT DO NT WORK,AND RADIO IS SAYING LOCKED UP


Does the vehicle start?
If not, then check battery voltage. If below 12.5 volts, then recharge the battery and retest system charging voltage (should be around 14 volts)
If battery is fine and vehicle starts, then check fuse box and wiring loom connectors.

Sounds like you have blown fuses which could have happened if you accidently short circuted something while wiring up the new stereo. Check your fuses to see if any of them are blown.

The easy part of this problem is knowing what it is, the difficult part is finding where it's shorting out. With the meters of wire and harness it would be discouraging thinking about it. Knowing VW took a lot of time engineering to avoid this simple problems, there are conditions that couldn't prevent this.

First off, have you recently installed an aftermarket part that hooks up to the wiring system e.g. radio, gauges, gps or other electronic accessory? Something added that needed a harness moved to make it fit or needed splicing a wire to power it up?

There are times when doing electrical work, the person doing it doesn't realize while stripping insulation from new wire that a strand of wire fell in a switch, fuse terminal causing a short in it's circuit.
You'd need to clean the fuse area with a clean paint brush to dust off any metal debris. Another way is by simply using a digital VOM with continuity tone to single out which component is causing it to blow the fuse.

Another suggestion is use a VAG 1552 scan tool or equivalent. This will also help pinpoint which component to look at and narrow the search area.

If you're a DIY kind of person and want to know how your vehicle works, wanting to get a little more involved. You'll need a Windows based laptop and purchase a ROSS-Tech software by clicking on the address.

The windshield wipers, the power windows and the heat/AC stopped working at the same time on my '95 ford Escort.


based on what I see in the ford electrical manual. The ignition switch is the only thing the windows, wipers and heat have in common. I would test for power at the black and red wire with the key on. If there is no power I would replace the switch.

cheapist way is too go to your local junk yard and get the items of a clunker? be sure you cut the harness to the radio ac etc so you can match up the wires ? remember you need to write down the seriel and model # off the junkyard radio so you can call the dealer and get the radio anti theft code its 5 digits like 25143 etc,, they have that info if you call the dealer
