Blower not working at all. Fuses & relays ok. Aircon cuts in when fan is turned on but no air from vents. Need to know what colour wire supplies power to the blower before I assume the motor is faulty


the blower is silent.????????? yes, sounds matter !
ON HIGH TOO? (fan speed max)????
or makes normal sounds, but does not blow.
1 or the other.?

the blower if dead silent can be hot wired (blows now?) (costs zero to do)
or using any voltmeter made. measure for 12vdc on the 2 pin
to motor, fan on high. (costs $10 for tool at walfart)
if 12vdc there, (across the 2 pins) then the fan is bad.
of 0v, the controls are dead.
the fan on most cars. on high, bypass the fan speed resistor block.
what you dont have is the schematic,
its at 2 places (usa ,min)
alldata.com
and suzukipitstoppus. (real fsm book)

2000 GV, data, below.... it takes all of 10sec to look.
all answers, USA cars, as this is a USA forum.
i click HVAC for you.
as you can see the switch is grounded at red circle.
and with fan on high ground (0v) is applied to the motor low pin
and if the relay is hot, (2 fuse good) the output of relay b/w wire
will be at 12vdc, if not the relay is bad.(fuses good)
cant be more simple. same from 89-2000 after that things get harder, (controls) your car has a motor driven mode damper
that is why i asked the sounds questions. as it too can block the air flow. (with a perfectly running fan)

I have a Samsung HL-P5067W/HL DLP tv. When I turn it on cold the lamp light blinks on and off. The fan makes a high pitch sound a relay clicks the TV goes back to standby and the lamp light starts blinking...


This sounds like a lazy lamp--that is getting hard to start. Try a new lamp first. If you are inclined to do so--get a bard bulb and install in the old lamp housing and save some money. Get a real PHILLIPS bulb--it will last a while--compared to cheap generics that are good for maybe 6 months !!

Hello

High pitch sound comes when the main control also known as the electronic board goes bad and needs replacement. Please try to blow air with hair dryer on the display just to check if that'll solve the problem. Hope you understand...If it does not then replacement of part is only recommended repair. Please get back to me if you have any other questions.

Will not turn on, red light flashing next to the menu button


if the fans don't turn on, they may be bad and needs replacing or rewired. if the fans turn on but not the lamp, the colorwheel may be bad (listen for a high-pitched whir when you switch it on. if no whir, replace the colorwheel). if the colorwheel is ok, replace the lamp.

LG makes a high pitched sound during water add cycle


Hello.
The high pitched sound is a definite sign that the water valve in use is failing. The squeal is from a restricted water flow through the valve because it is not opening all the way. You will need to choose cold or hot to narrow down which valve is bad and replace that one.
