Toyota 2002 Sequoia, the two front windows will operate only from the drivers door control and the two rear passenger windows and hatch door window will not operate from any interior control. I can operate the hatch door window with a key in the door and can let in down with the remote.

Check the drivers side window lock button, press it down to unlock it and the other windows will begain to operate. This is a safety feature so if you have kids the windows can't roll down using any other switch but the drivers side master window swi ... 2002 Toyota Sequoia

Have a 2003 Chrysler Town and Country Limitied van utilizing zoned climate control with a ventilation problem. While the climate control board is off, the fan motor still operates near full speed. Turning on the control panel will get you temperature control, however, there's no control over fan speed. Almost seems like the fan control dial is stuck at full throttle, on or off mode. Is this a control panel issue or is it a relay behind the glove box? thanks for the help.

On an 03 Bravada, blower fan does not turn on. It does sometimes operate at a very low fan speed. It however cannot be controlled, or either turned on or off. When the car is shut off the fan will not shut off and eventually the battery will go dead. The battery has to be disconnected. The higher speed fan may occasionally come on when the car is started, but there is no switch control and turn on is at random and not at will of the operator. after the car is shut down, the fan continues to run,

I have a 2002 Jeep Grand Cherokee Limited with the automatic climate control option. Within the last few weeks, I have noticed cold air seeping under the passenger side dashboard, near the blower mechanism. It seems that the faster you drive, the more air comes in. I checked the heater operation and found that it does blow hot air out of the floor vent at the same time, so the climate control is operating correctly. Could there be a poor seal around the blower assembly. Any help would be appreci

My 2004 Lexus LS430 Navigation goes in and out, mostly out. When it's not working, the screen is black and I cannot operate the climate controls, radio/CD, etc. I could live without the navigation system itself and even the audio, but climate control is important. If I have the a/c on when the nag stops working, the a/c will continue to operation unlike the radio which will shut off. So I keep the a/c on all the time. I'm not even considering paying $7600 the dealer said it would cost to replace

Intermittent problem. 93 Lincoln TC with Automatic Temp Control. Sometimes the defrost position won't allow heat to windshield. Sometimes heat comes out of vent when everything is off. Sometimes A/C is in operation and won't come out the vents. I can usually 'reset' A/C by shutting it off and letting hot air in car. Sometimes everything works perfectly. The auto side doesn't work at all. I've been operating in manual for a year. Is this a sensor? Vacuum module? Or Control head?

Hello and thank you for your knowledge. I'm leaning towards the cabin air temp sensor. Where is that exactly? I've replaced the blend door actuator. This problem is so intermittent-it's crazy! For over a year the Auto feature hasn't worked. Today, if ... 1993 Lincoln Town Car

I want to check the fuse of the cruise control in my 1998 audi a6 quattro. I found it in the manual. There were 2 fuses for the cruise control # 5 and # 11. I've checked #5 and it was OK while #11 doesn't exist. The more strange thing that #11 doesn't have two metal pins inside the fuse box. Does this mean that I don't have a cruise control system? Knowing that I have the lever for operating and setting the cruise control system in my car, the system didn't work since I bought this car (a year a

I have a 1999 Toyota Sienna. The used dealership had a passtime device on it, and they finally removed it. Our headlights just quit working, so I went to,salvage yard, and got another headlight switch. Did not fix it. The 15A fuses that separately control each headlight did not correctly control them, so I swapped out the fuse block under the Hood, and the fuses operate normally now. But I still can not get the new headlight switch to control the headlights.

My van has dual air controls for the cabin worked from a verticle slider with the two controls. Drivers side works normally but it blows hot air from the passenger side, even when the slider is set to the lowest (cold) position. The air conditioner operates normally, blows cold air onto drivers side only, although I assume it is mixing with the hot air coming into the cabin on the passenger side. What is causing this? I am suspicious of the temp control slider.

The problem is almost always caused by what is called the Air Temperature Control Blend Door Actuator Motor, I have not seen any issue with the slider that sends a signal to the door to blend heater and AC air streams to give the desired outlet tempe ... Oldsmobile Silhouette

Main control module on driver's side does not operate the driver side window or the other windows. Also, sometimes the driver's seat heats up. *** It was raining one day and I went to let up the windows and the switch seemed to short circuit and would not operate the windows from the main module. The three other windows work but have to be operated individually at their respective door. *** What is the problem? Does the entire module needs to be replaced?

Ac/heating problem I own a 2000 dodge grand caravan. This morning I turned on the heat and nothing happened; so therefore I tried my A/C and nothing happened. My A/C operation button, recirculation control button, blower switch, and mode control switch suddenly stopped working. It allows me to push the buttons and turn the switches but nothing happens. However, I did notice that the temp control panel was getting hot to the touch. What is wrong or what do I do? Please Help!
