Honestly. Dont bother. If you are still wanting too look it up and you will see all the money you will be throwing away to try this, the best bet it to reflash the memory mods and set the gov to 0.

Yes, it works perfectly. It has a new model number because the old model is known to fail. Keep the plastic cover from your old clock to cover the little white plastic part on the clock.

2007?? my book says dealer diagnostic machine only sorry about this but i have just looked it up and pre 2005 it can be done but from 2005 dealer only ,like changing the brake pads its a dealer only job

Actually, it can be replaced on the 2007. I own a mobile auto repair business and replaced the damper at my customer's home.

If you notice, there is not enough room to lift it straight out because of the head on the M273 V8. You will have to remove the belt and take out the bolts for the Tandem pump so you can tilt it enough. The front bolts are not that bad. There is a bolt holding the pump in place that you will need to get to from underneath. Once you have removed the bolts, you can move the pump far enough to unscrew the damper and take it off.

i would recommend a universal wrech.Thanks for asking and I hope this helps out.Please leave me 4 thumbs up.

in your fuse box is a service reminder reset button, if not in your fuse box under the dash it will be under the hood fuse/relay case.

every 7000 miles should be fine. once a year???? what if you drive 20,000 miles a year??? don't sound right to me.

U HAVE TWO FUSE BOXES IN THE FRONT , ONE ON TEH RIGHT FIREWALL AND ONE ON THE LEFT DRIVERSIDE FIREWALL. ITS USUALLY THE DIRVEERSIDE FIREWALL. SLIDE THE TABS FOR THE COVER TO THE UNLOCK PICTURE, IT SHOULD BE A BLUE 15 AMP FUSE. EASY WAY TO CHECK IS IF THE CIGAR LIGHTER LIGHT TURNS ON WITH THE HEADLAMPS ON THEN ITS GETTING POWER . YOUR CIGAR LIGHTER IS PROBABLY NO GOOD.
