Blower is used for either AC or Heater demand. If it doesn't work in heater mode, but work in AC mode then it is a problem with the Climate Control. If it doesn't work in both cases, then check the fuse near the front fender on driver side ( It is not in the fuse box). If the fuse is good, then it is not necessary the blower is burnt, but the blower regulator is burnt. The Blower regulator is underneath of the blower. It can be accessed from the engine side under the wiper motor.

Your rear turn signal flashes fast because the front is not working. Most likely you have a burnt out bulb in the front. If your A/C compressor can be turned over by hand and doesn't lock up or make any clanking sounds it's probably alright. The compressor will not run if the system is low on refrigerant. If you're having problems with the A/C and heater controls, that would be the first ting to repair. It doesn't sound at all like any electrical problems.

My 1988 chevy silverado blows the heater/ac fuse when engaging 4w


There is an electric actuator on the front axle that engages 4WD. This part commonly fails resulting in no 4WD. Unhook the electrical connector to this part and see if heater still blows fuses. If It does not blow the fuse, the problem is in the actuator. If it still blows the fuse then it could be in the wiring. Buy a repair manual and trace the wiring schematics.

there should be a plastic guide clip either in the glass itself or built into the window runner really you need to have the door pannel stripped down to see the problem as for the rear window its one of two things either the switch or the motor itself .to test it try operating the rear window from the front switch and also the rear one if the window works then you need to replace which ever switch didnt operate the window

While in park 1988 mercedez benz 190e idles rough and sometimes


This is an interesting part, and I spent quite some time to fix the problem. I list it here those steps in the order could fix the problem ranging from least expensive to most expensive steps. It just happened to me the last one really eliminated the problem. 1- Make sure it gets turned up first. 2- Adjust cables to increase idle. There are two cables. You remove the air filter to see them clearly. a- one for the gas, the other for transmission. b- clean the area well so you can see a micro switch. This switch called cut off switch. c- whatever adjustment you make, the level of the switch has to press on the switch to maintain the idle. If you see it off, you can bend the metal part to keep it in place 3- Take off the Fuel distributor to clean the throttle below it. 4- Replace all the injectors. These are not Electronic Fuel Injectors so you don't have to deal with Injector module. 5- Replace the fuel distributors. Good luck.

1988 Ford Exppedition heater in the front will not work


I ASSUME THIS IS A 98, THIS PROBLEM IS CAUSED BY A PART CALLED AN "AIR TEMPERATURE CONTROL BLEND DOOR ACTUATOR MOTOR" THIS MOVES A DOOR BETWEEN THE COLD AIR FROM THE AC AND THE HOT AIR FROM THE HEATER CORE, YOU WILL NEED TO REPLACE THAT ACTUATOR. .

1988 BMW 735I Defroster blows hot air... I getting a sunburn


The Heater Control Valve has failed. It defaults to full defrost mode when it fails and blows hot air even when the A/C runs. Replacement part is $105 ...google Autohaus AZ for online parts ordering. BTW...HCV is located in the engine compartment right in front of the driver position in the corner by the firewall and inner fender...you'll see small coolant hose running to it.

Driver's window


I have the same problem, its more than likely a sticking motor. I just punch the door panel below the window switch (where the motor is) and it works. You may have to bang it a few times but i have to do it about once a week on the front right or my car.
