Ever see shows like "Pimp My Ride?" Are you a fan, or do you think they're just ridiculous?

Asked by JimBones about 11 years ago

I really have mixed feelings about those shows. On one hand, they are totally ridiculous. Adding things to cars that BEG to be stolen. On the other hand, some of the work those guys do is really awesome. I have become very jealous of the folks that do upholstery work. Being able to sew custom seats, and dashes is really awesome. Basically, when they make custom stuff, I am on board. Adding 57 TVs is dumb, but making the custom enclosure for it is awesome, and a skill I wish I had!

Looks like you've touched on this, but HOW do mechanics rip people off? Is it just as simple as telling customers they need unnecessary repairs?

Asked by bowlingfersoup over 10 years ago

Sorry for the delayed response. I wrote an entire post talking about this exact question. Please let me know what you think..

I just took my '05 Expedition in for a tune up because the check engine light was on and it needed to pass emissions testing. It is now running way more rough than it was and the check engine light is now blinking at me. Do I have any options?

Asked by seth_208 about 10 years ago

Sorry for the late reply. I hope that by now you got your Ford fixed. I am guessing a coil was not properly installed, or failed.

If you can, update your question so we all know what fixed your car.

My a/c will not work. 1996 Mazda B2300 I have checked the fuse, it is charged, and the compressor will cycle on and off, but it will still blow hot air. Anybody have any insight on what it could be?

Asked by kelly over 10 years ago

Hiya Kelly,
This is a pretty crappy time to have no a/c isn't it. It was 96 yesterday where I am YUCK!

Okay, back to your question. Can you give me a little more info?

  • When you say that the compressor will cycle, do you mean it cycles properly? Or does it turn on the right back off?
  • Does the cooling fan on the radiator work properly?
The other thing you need to check, is the vent temp ACTUALLY set to cold. Now, I know that you have turned the knob to cold. There is a door that moves to change the temperature of the air. I have seen the cable come loose on that temp door. You move the knob, but the door doesn't move.

The best way to check that is, with the car off, turn the knob back and forth a few times. You shoud hear a little thud. That is the sound of the door stopping at the end position. You can also look under the dash and have someone else turn the knob. Look for a cable or an arm moving.

Hope that helps. When you get it fixed, please update us with that was wrong.


What do you auto mechanics wear on the job? Is there a particular kind of clothing or fabric that can stand up to grease etc, or do you just assume whatever you wear is gonna get destroyed?

Asked by playball! over 10 years ago

We have a service that cleans our uniforms. Off hand I don't know the material, but I will check for you. I pay about $200 a year for uniforms.

Why Does My 2000 Dodge Caravan Alarm comes on by itself when no one is around ?

Asked by Steve over 10 years ago

Generally it is a failing sensor. It could be for any of the door sensors or the hood or trunk. 

what would make my 92 Honda accord Lx chug and sputter at 2000rpms and not go over that even when I have pressed the gas harder

Asked by jennifer monness about 10 years ago

Hey Jennifer, it could be a number of things. I always recommend starting with normal maintenance. 

That symptom is also common with a clogged catalytic converter.
