If your blend door or doors are broken sometimes you will only get cold air coming thru the vents or maybe just hot air with no air conditioning. A blend door is short for Blend Air Door. There are other names such as temperature door, etc.. The blend door, blends or mixes the hot air with the cold air. There usually is an actuator motor that opens and closes the blend door a little at a time to adjust how much hot air and cold air to mix for the temperature setting you have chosen.
A common design flaw in these systems is the end point detection for door movement. The catch is that over time the plastic doors cannot withstand the over-stress of the calibration routine and will break. When this happens, all control over heat and AC is lost. https://www.facebook.com/pages/Simpsons-Mobile-Auto-Repair/108636635836373

Save money on towing costs for breakdowns with Simpsons Mobile- Mechanics- our car repair services come to you. Just about every late model car and truck use a serpentine drive belt. It is a single ribbed belt that drives all the accessories, A/C, Power Steering, alternator and various other pumps and accessories. They should require no maintenance unlike their predecessors the V-Belt that needed periodic adjusting. But the fact of the matter is they don't last forever and they do need to be inspected often to keep you from getting stuck. If it starts to go bad, you can replace your serpentine belt at a time of your choosing and not when the belt decides for you. Checking ribbed drive belts at every oil change, and the position of the self-adjusting mechanism indicator, will insure you catch a bad belt long before it snaps.The backside of the serpentine drive belt, or the smooth side, usually drives the water pump. If the serpentine belt gets oil soaked or glazed, it will slip and not provide the proper circulation to keep the engine cool. And if there is oil on the serpentine belt, it's coming from somewhere so you will need to find out where and fix it before putting on a new serpentine drive belt.
Look for tears or abrasions. If you see any it means the serpentine drive belt is rubbing a pulley flange or bolt as it winds it way around. This will happen more often as the drive belt gets older. If this happens you may need to file a pulley flange smooth or bend something out of the way. Also look for pinholes and/or bumps. If you see any it means dirt and debris is getting in between the serpentine drive belt and the pulleys. Turn the belt around and see if there are chunks of the ribs missing. You can crank the engine to expose sections of belt as you inspect. A few, small widely spaced chunks are okay, But if there are many and/or close together, replace the serpentine drive belt. Hairline cracks are normal, but if they go into the backing, or flat side, of the serpentine drive belt you will need to replace it. A good rule of thumb for serpentine drive belts is that if cracks are observed 3 mm (1/8 in) apart, all around the belt, the belt may be reaching the end of its serviceable life and should be considered a candidate for changing. Small cracks spaced at greater intervals should not be considered as indicative that the belt needs changing. However, the onset of cracking typically signals that the belt is only about halfway through its usable life. Electrical gremlins can haunt even the most well built automobiles. troubleshooting electrical problems can be a daunting task, but as long as you follow the right path, in the right order, you'll slowly eliminate potential repairs until you figure out what's really causing your car to malfunction.
Why Mobile Mechanic?A mobile mechanic can actually afford to charge you less due to less overhead in running such a business. This is what makes my prices the best in town! Additionally, when the job is done right, and a good mechanic will always do the job right, then your car won’t need to be fixed repeatedly.
Another thing that sets me apart is my longstanding knowledge of cars, trucks and vehicles. This is a job of passion for me. I love what I do. I am therefore extremely knowledgeable in the subject and simply understand the machine and will often find the problem that many other mechanics were previously having difficulty with or using the wrong solution for the problem. With the rapid advancement in technology, the mechanic's job has evolved from purely mechanical, to include electronic technology. Because vehicles today possess complex computer and electronic systems, mechanics need to have a broader base of knowledge than in the past. Lately, the term "auto mechanic" is being used less and less frequently and is being replaced by the euphemistic title “automotive technician”. Fading quickly is the day of the 'backyard mechanic', who thinks he needs little knowledge of today's computerized systems .
Brakes are one of the most important safety devices on your car. If you've even partially lost your brakes in the past, you'll remember the change of underwear that followed. Inspecting your brakes twice a year for wear and damage can protect you and your passengers while saving you money by catching any damage before it becomes too costly.
