SOURCE: Acura MDX A/C won't come on

I went to an Acura dealer to buy the transistor for the rear A/C unit. The service advisor told me that the problem with the front A/C was probably due to a defective front transistor / resistor. I bought that part too.

The front transistor is located next to the blower motor under the dash on the passenger's side. It is secured by three or four small bolts. The one on the bottom left is very close to the carpet and the most difficult to get off and put back on.

The rear transistor is located behind the carpeted trim panel on the center console (driver's side). The carpeted trim panel is secured by clips only - there are no screws, so remove it carefully starting at the side near the accellerator pedal. Once the panel has been removed, reach inside a small hole in the metal frame to access the rear transistor. It is removed by twisting it and pulling it out. The hole in the frame is small and you might find pliers helpful.

After replacing both parts, the front and rear A/C are working. Apparently these transistors are common failures. If the A/C is out in your Acura MDX and the fuse checks good, a new transistor will likely solve your problem.

SOURCE: 2004 Acura TL front end problem

You may not need the entire strut, just the part that serves as a shock absorber. The term strut refers to a complete assemby with coil spring and a central shock absorber. When their seals fail completely, whether gas or fluid filled,they are just a piston in a cylinder with nothing to damp their travel so they can slam at both ends.
American made 'shocks' were once only really effective for ~20k miles but both foreign and domestic have improved a great deal but one of yours may have left the factory less than perfect.
Shop the parts before you let the car go to anyone to see if they are scalping you or only marking their cost up a little.

Which fuse box on the 2011 Chevy Malibu is the fuse for the rear defrost


Fuse box rear , fuse #23 30 amp ! Do you know where this is located ? There is also a relay for the Rear window defogger , located in the same rear fuse box .
Fuse Block - Rear
Left side of the luggage compartment, behind the left rear wheel well . But you really need to know how it works , you can check fuse an relay .
Rear Window Defogger Operation
Battery positive voltage is supplied through the BATT 1 fuse in the underhood fuse block to the rear defog relay switched input. When the rear defog switch button is pressed, the body control module (BCM) energizes the rear defog relay by providing a B+ to the control circuit of the rear defog relay. This allows battery positive voltage from the relay switched input through the switch contacts and out the relay switched output to the rear window defogger grid. The HVAC control module houses the rear defog switch and also illuminates the rear defog indicator on the switch button, upon this request. Ground for the rear window defogger grid is provided by G301 for the Sedan or G302 For the Extended Sedan.

My rear defroster won't work I have a 2000 Buick Park Avenue


Could be a bad relay !
The rear defogger circuit is protected by a 40A fuse. Voltage is supplied through the fuse to the rear defogger relay. When you press the rear defogger switch, the heater and A/C programmer sends a class 2 message to the body control module (BCM), to ground the rear defogger relay coil output circuit. This in turn closes the relay contacts allowing current to the rear window grid.
Do you know what a class 2 message is ? What a BCM is ?

What is the fix for a rear defroster that doesn't work?


when you push on the rear defroster button does it light up if so then you will have to use a test light and check for broken window grid wires on the rear window. you ground one end of the test light and using the other end start at one side of the window that lights it up then follow the grid line from one side to the other at 2 inch increments, the light should light up but get dimmer as you test the length of the grid, then go to the next grid line and repeat. when the light stops lighting this is were there is a break in the grid is and needs to be repaired. you can get window grid repair kits for this.

Defogger window wont work


front or rear.?
my guess, wild is, the rear electric defogger, is dead.
the test is so easy.
attach any voltmeter to the 2 grid terminal. and turn the defroster on.
12v there? yes, then the grid is open.
no> the relay that feeds it is bad. (or its controls or FUSE is blown)
check all fuse first.

Rear defroster doesnt work already reset breaker and check fuses but one fuse in manual not on panel


i think this is a grid type(wires) rear defroster as opposed to a fan style.then when you push the button to turn on the rear defroster you should hear a click this tells you the system is working from the fuse to the rear window.what you have to do is check the rear window grid(wires) with a test light and you will probably find some of the grids not working which indicates a break in the grid line and needs repair.you start with a test light at one end and you should see it light up brightly at one end of the grid and as you move along the grid wire to the other side of the window you should see the light gradually get dimmer,when you hit a spot were the light stops working you just have to norrow down the area of the break and mark it with a marker below the grid,when you have done the complete window you will know the areas that need repair.you can buy a defroster grid repair kit and repair it.follow the directions.before checking the grid wires check the area where the car wires connect to the window at both sides of the window.sometimes there is a problem in this area.

2005 rear defrost switch light works but window does not defrost. Window grid has continuity and there is power to the window wires but when I connect the wires to the window no power shows. Now my rear...


Check for good wiring to the grid.Take the two wires off of the grid and use one end to a load[such as an old headlight bulb or what ever you can find that pulls around 5-10 amps].A test light can be used but it draws no wheres near as much power as the grid does but it will get you started.Put a test lead from each of the grid wires to your load source or test light to see if it works or lights.If the load is dim or turning slow[if all you found was a fan motor or something like that] then you need to find out if it's a bad ground or a corroded power wire.Put the load from the power side to a good ground elsewhere on the vehicle and if it works normally then you have a bad ground.If it still doesnt work like it should then you need to trace the power circuit wiring.This is not brand specific it's just general electrical trouble shooting advise so i hope it help[s you out,a volt meter will show you voltage even if only one strand of wire is still connected so this should be doe when ever electrical problems appear to be normal but still don't work.

2004 acura TL cruise control wont engage...need to get fixed


This is a problem you will to take to a shop, If you are mechanically inclined I can help you, but if not I would not mess with it, it could be the button or it could be the controller and could even just be a fuse, check the fuse and if you don't find the fuse blown then let me know if you have a volt meter and what to test this yourself. You are going to be working around the air bag too and if you probe the wrong wire while testing you could break your arm or leg by deploying the air bag by accident. Or your neck.
