SOURCE: I have a 1993 cadillac fleetwood. All the lights

You need to replace the twilight sentinel day time running lights module.Also be fore replacing it make sure you have a power supply comming from the pink wire (from ignition switch to the Module).engine running.There is only one pink wire going to or from this module.If no power, then replace ignition switch first. Good Luck and have a good XMASS.

Hi there,

P0030 = HO2S Heater Control Circuit (Bank 1 Sensor 1) - No.1 Heated Oxygen sensor on bank 1.
P0036 = HO2S Heater Control Circuit (Bank 1 Sensor 2) - No. 2 Heated Oxygen sensor on bank 1

For both of these to trigger on the same bank, means most likely an Open or Short to Ground condition (somewhere on the Bank 1 circuit) stopping the HO2 sensors from reaching their working temperature.

Check the following in this order:

1) Using a multimeter, check 'continuity' of the Oxygen circuit FUSE terminals (don't rely on visual inspection alone) or replace fuse with a known good one.
2) Check for moisture getting into both oxygen sensor connector terminals (bank 1).
3) Check for good connection at Oxygen sensors (bank 1).
3) Have both heated oxygen sensors on Bank 1 tested (ensure their values are to specification).
4) Check HO2 pin-outs of the PCM for correct voltage.

Only replace the HO2 sensors as a last resort (if out of spec).

Then engine department relay centre & fusebox location is behind the washer bottle, but I believe the HO2 sensors are connected direct to the PCM, not a relay.

1998 Oldsmobile Cutlass, sunroof is stuck open and it goes back and lift up but it won't shut. Cpuld it be a fuse? If so wheres the fuse located?

When pushing close switch?
are any sounds from switch,
is any movement to window,

The fuse can be found in one of two places. Fuse box on driver side lower dash by driver door.

Relay Fuse Center, under the hood, upper driver corner.

A bad fuse would cause NO POWER to sunroof. IF window moves back and up, fuse is good. Cause for not closing, or moving forward would be wire connection to forward/close switch, or a bad switch. Also could be window track.

Checkand clean sliding track, window could be geting stuck on something.

Check wiring to switch, this means pulling the switch.

Tried it today and none of the windows work from master switch on drivers side except ft passenger window, which went down but will not go back up.

You can't put up the front passenger window with it's own switch ? Did you check the POWER WINDOW RELAY in the instrument panel fuse / relay box ? An you checked POWER fuse 30amp same fuse box ? All window switches have direct power from power window relay !

Convertible top

Taken from answers .com There are several fuse boxes on the Cadillac Allante. I know that, in particular, the 1993 Allante has a fuse box in the trunk, right next to the battery, underneath the ashtray assembly, and then one more in the engine compartment. For the one in the trunk-- lift the trunk. Facing the rear of the car, looking at the back window, move over to the right rear wall of the trunk and flip up the panel there. It is a carpeted panel that is not obvious. Shake that panel a bit and you will see that you can flip it up. I believe it has some Velcro tabs that keep it down. There is a fuse box sitting there inside the shell of the body once you open that flap. You won't miss it. For the one by the battery, which is located within a shelf behind the passenger seat---slide the carpeted shelfing facade towards the passenger's seat.

1989 Allante windows not powering off after 10 minutes or door opened

The window switches would not drain the battery, but the lights could.
Is there a timer for just those lights, or all of the courtesy lights ?
How do the door switch lights get power ?

I have a 1993 mustang 2.3l convertible, and my driver side windows wont go down and i wanted to know if i could switch the horn relay with the window relay

do they have the same part #? If so, you'll be okay for sure. You can also check their amperage rating, since most automotive block relays are wired the same (in case one is not original). If the amps match you should be good to go.

I have a 2003 hyundai sonata the power windows stopped working, I have changed the fuses and checked the child lock safty..nothing works what else could it be

Dear kaydynandtri, If you have the owner's manual find the power window relay. They are usually located in the fuse box. Check to see if there is another relay that matches that one and switch places with them. If the windows work or the accessory the relay came from does not the relay is bad. If this does not work I would replace the driver's door power window switch. I have also seen the wire break on older cars where it goes into front of driver's door.

My windows on my 1993 subaru impreza won't go down

if its just one window it could be the window motor / switch /window regulator but if its all of them its more likely a blow fuse or a bad relay check for blow fuses and you can check the relay by interchanging it with a know good one( for example if your horn works and the part number on the relay is the same as the window relay swap them and see if your window work the relay should be under the hood and the fuse box should tell you which relay is which

My power windows do not work. The Haynes Repair Manual mentions that it could be that a circuit breaker was tripped and might need to be resetted manually. Where and how do I manually reset the circuit...

i have diagram for accord 1993, i cant see the breaker you mentioned, if your relay is ok, its mean that fuse #15 have power 12V and when the ignition is on, the relay have supply 12V to fuse #33, if all this ok, the problm is on your power window main switch, connect a wire supply by 12V to white/yellow wire at power window main switch or test this wire if already have 12V when ignition is on
