Its called a blend door actuator, it contains an electric motor and gears that operate the blend doors over time the gears strip out inside the actuator,it needs to be replaced, and can be quite a job to get to my advise is to take it to a local dealer, they know the product and it may not be as costly as you might think..

Where is the turn signal relay on a 2000 Mitsubishi eclipse?


It is behind the radio. So you will need to take out your center console and radio to get to it. It should be a little black box. If your turn signal still make a clicking sound, you can put your ear near it and hear the clicking sound.

92 ford ranger i turn the wipers on and only here clicking why?


Just guessing, but sounds like the rod that connect the wiper motor to the wipers has broken or the just a clip came off the wiper arm. You can see the wiper arm through the cal panel in front of the windshield. If not, the cal panel will have to be taken off to get to it. Good luck.

2003 MITSUBISHI GALANT 2.4, THE CAR WONT CRANK! TURN THE KEY TO CRANK AND NOTHING. EVERYTHING LIGHTS UP ON THE CLUSTER, YOU CAN HEAR THE FUEL BUT THERE IS NOTHING GOING ON AT THE STARTER. HAS A NEW BA


Starter relay is actually mounted on top of the starter. Have you checked to see if your "new" battery was fully charged? If it is, then i would try a new starter which comes with a new starter relay. If you don't think its any of the above, it must be your starter switch. NOTE: starter switch is not where you put the key in, its mounted somewhere on your column, maybe even close to the floor and is actuated with a rod. You can actually start your car without a key after you find where the switch is located. Just pull down on the rod. (little known fact you can start a car without a key this way, hope your not a car theif, you can steal anycar this way lol)

How to manually open the dampers


I have a 91 deville that never had a working heater. I fixed the prob by unhooking the actuator, or blend door motor. Now i have defroster, and heat comming from floor, but no vents. The actuator is behind the trap door in glove box, its a black box with a rod connecting to the blend door. After unhooking, make sure the blendoor is all the way to the right, i wired my in that position. Heater works good, and have had no probs. Hope this helps

Defroster does not work. Only A/C/Heat from front vents, even when set to defrost. Suspected panel/defrost Door Bend Actuator. Any suggestions?


Yes, it sounds like a blend door actuator problem.


By Jeff Frank First you have to remove the glove box to gain access to the plenum. Next, remove the actuator from the box. The actuator is a flat white box that sits on 4 clip posts on the top-left of the plenum. It has a wire harness coming out of it. To remove it take a flat screw driver and pry up the front first then put the screw driver under and towards the back to pop up the back. You will see a white pin coming out of the bottom of the actuator. The pin is "D" shaped. Turn the ignition on and move the heat control and you should see the pin rotate. If not, the actuator is bad or the terminals are corroded. If it does move, set the control to full heat and turn the blower on high. This will force the blend door into the heat position (it is very important to do this).
Take a small dentist mirror and a flashlight and look into the top of the box where the actuator pin goes in. You should see that the chamber is half missing. It should look like the drawing below:
1-1.gif I think they all break in the same spot. Mine was in the position as the one above. Remember you are looking through a mirror so it is a little difficult to determine the exact position. If yours looks like mine did drill your actuator pin in the same place I did. If not, try and gauge where yours will need to go. I had to drill mine four times before I got the right position. I drilled mine with a very small drill bit. If you are looking at the pin from it's bottom, this is where it should be drilled: (drill about 1/2 inch from the bottom)
1-2.gif After drilling the actuator pin hole, you will need something to put through it. I used an old drill bit that was the same size as the hole. Just cut it to length (you will want a little more than 1/8th inch on either side of the pin). Put the rod through the pin (it should be snug so that it doesn't fall out). Then try snapping the actuator back on the box. If the pin won't go in fully the rod might be in the wrong place. Try turning the blower on high again to make sure the door didn't move and try again. If it still won't go in you will have to re-drill the hole. If it does go in, try the heat controls. If they work, congratualtions! Now take the actuator back out and glue the rod in place and put the actuator back on. You just saved yourself $1000. If only the cold or heat works, then either the rod is in the wrong position and will need to be re-drilled, or the door itself is also broken.

It sounds like you don't have a ground going to those areas. I think I would check for a ground...maybe pull the fuse on the rear defroster and see if it is even a part of the problem.

NO AIR OUT OF THE FRONT VENTS, JUST OUT OF THE DEFROST TOP AND BOTTOM


I recently solved this same problem, look under the dash and there will be a rod that connects to the black exchanger box and most likely that rod has come undone and is not switching like it should

Auto windows not working on driver and passenger side front


This could be an issue with corrosion of the relay between the switch and the motor (little black box).

Sometimes the glue that holds the motor's "piston" to the window will stop working, and the "piston" will slip off the window, causing the window to stick in the down position as well. As long as your doors are apart, you might want to check that too.

For the windows to work, you may need to find a new relay, or possibly a new motor. They can burn out or have other problems in excessive heat/use/age. The GOOD news is that pretty much every salvage yard will have 4 or 5 1987-1991 Oldsmobiles sitting around, so you can steal the parts for next to nothing. Also, Buick LeSabres (also 1987-1991) are almost identical to the 88's, so you can use those for parts too!

Best of luck!

Rear window defroster wont work.


First place to check is under the wide trim piece that runs over the back drivers side door and also runs to the back window. You can pull this away from the body. It just snaps in place and the seatbelt goes through it. Pull it down toward you and you should see a black box fastened to the side of the window pillar. It should have three wire connections. One is the radio antenna, one goes to the window and one comes from the wire harness. Check the two wire connections from the harness and to the window. See if they are loose or in my case the one from the harness was burnt and had melted the black box where the wire went in. I had to replace the the wire connector and the black box ($72.00) and replaced the connector terminals. The replacement connector is available but that little thing is pricey ($32.00). They must be proud of that thing.
Hope this helped.
