    CRAZY electrical problems after DVD head unit install....HELP!

    Got my new DVD head unit installed. Now I have numerous electrical problems

    I have a 2003 Chevy 2500hd

    1. HVAC will only blow through the defrost vents. I can control the temp, the fan speed and ac/ no ac. But it only blows through the dash vents

    2. When the deck is off everything but the HVAC works great. I turn the deck on and BLAM...the gauges all shut down, every warning light on the gauge cluster lights up...the DIC reads UNKNOWN DRIVER


    WTF is going on...anyone?

    thanks in advance

    Did you install or a shop? If a shop, take it back. If you did it, there is a short somewhere or you crossed a wire.



    Current set up: Island bombed out 92 mazda 626. Stock rust bucket

    66 Pontiac GTO, modified stock radio, Crossfire CFA 302, Kicker KS6.2's in the front kicks, Crossfire CFA 452 for the 6x9's I need.

    2003 chevy ehh....if you installed it, did you hardwire, or use a harness? And if you did use a harness, was it a CAN-BUS harness?

    they messed up big, and it's wired into databuss wires...... they should have known better, especially when it screwed everything up.

    i buy broken amps....
    No, i will not "gift" paypal. please do not even make it awkward by asking. if the fees are an issue, I am usually inclined to add them. unless you have discount elsewhere, shipping is through usps flat rate, through usps parcel post, or through the roof..... i am in alaska. thanks

    Take back to shop. Go in pissed and get it fixed and with the right attitude might give u a discount on any future product you buy. I wouldnt let them install anything in my car again.

    Re: CRAZY electrical problems after DVD head unit install....HELP!

    Fuggin dumbazz installer ran a deck speakerwire to the class 2 buss wire DERRRRRRR

    "We are a professional installation center, very knowledgeable with Chevy Silverados."

    When they pulled the deck, they told me nothing was wrong. I asked to take a look at it. I immediately saw a bi-colored wire, usually speaker wire, mated to the buss wire. They said nothing was wrong, and that it was my electrical system. I took the dykes from the installer and clipped the wire, started it up, and what do you know? All my gauges, windows and interior lights worked

    I gave the owner a piece of my mind, left a **** in the toilet without flushing it, and left. I have a good mind to send that douche a bill for MY time.

    Thanks again for all your input
