Why are the fans not coming on in my 1999 deville


99 Deville - have you checked the large fan fuse(s) under and behind the main fuse/relay box ?? (I think this holds for 99 - 2000+ moved the maxi-fuses to the underhood box on the passenger side.)

Also, are your relays on a mount down near the fans ? Some have had trouble with the wiring/sockets there. 2000 or later moved the relays up to the fuse box itself. There are 3 - Fan 1, Fan 2, and a series/parallel (S/P) relay for slow and fast speeds.

Fans run in SLOW at 224 degrees F, FAST at 236 degrees F if there is no air conditioning or DEFROST function set. In the city or heavy traffic the gauge will go to the first tick mark past 12:00 and the fans come on. As the coolant lowers to 213 degrees F the fans turn off and the cycle repeats.

IF you set an air conditioning function, then fans run in SLOW all the time.

If your fans will not run under any conditions, check the large fuses in the underhood fuse/relay box, as well as the small fuses for the fan relays - there are 3 relays: Fan 1, Fan 2, and S/P (series/parallel): the fans are relay set to series operation (voltage drop) for Slow speed, parallel operation (full voltage) for Fast.

Carburator settings


If you have played with them the only way is to get it going pretty well is" ....
find the idle screw - usually larger - and turn in 1/2 a turn - hopefully that will keep it running - then find the 'slow' running screw turn it in until it stops then turn out 1 and 1/2 turns. Leave the fast one alone.
Get it started then adjust idle screw so its faaster if need be.,, now slowly turn the 'slow' screw in then out say 1/2 turn and listen for it either speeding up or slowing down leave it at the point where it sounds ok and try giveing a few 1/2 speed rev ups. If it goes back and idles as before - leave it.

The fast screw... (first make sure your exhaust outlet is totally unblocked - the slightest restriction here will cause it to never run right at high speed). Start it up and then try full throttle - same thing as before try adjust the fast screw first in a little then out until it runs well at what seems the faster speed it can - then check that it accelerates well from idle to full speed. If not adjust it a little more until it does.
Once it will idle ok and return to idle and also run full speed, then you can back off the idle screw until it will idle without the chain racing arond the bar.

Bear in mind th chain wil be racing around while you adjust it so keep fingers kids and idiots well away..because you are adjusting it with that chain moving..

I just installed a Hunter five minute fan which says it is called the augusta. I have also installed several other hunter fans in my house through the years, and they seem to move extremely fast especially...


Speed is not a factor in moving air. You can move air with a little fan that runs real fast or you can move the same amount of air with a big fan that moves slow.

It is the pitch of the blades that moves air. Big blades with steep pitch moving slow are comparable to little blades with shallow pitch that move fast.

It seems to me someone is trying to baffel you with bull**** when they tell you CFM = watts or something similar.

The real question is, is the fan moving the air necessary to achieve the result you desire? If yes, speed is not really a factor.

Let me know if this helps you.

Poulan chainsaw 46cc 20" chain


You normally have 3 screws - idle speed - slow running and fast running.
First take care as if it runs faster than idle speed that chain will be whipping around also.

Second you have to determine what is the problem. Is it faulty at low speeds or high speeds ? or won't it idle.
If it has turn stops fitted to the screws you only have a small adjustments either way.

If it won't idle, try turning in the idle screw a half turn - until the chain just starts to move slowly.
If its dying at slow speeds, get is going and slow turn the slow screw out until it starts to run a bit rough then turn it back in to the point where its running smoothly.

Bad fast speed can be caused by simple things such as a blocked muffler ( insects too - I had one blocked off by a mudnest wasp) - otherwise get it running at full and adjust the fast screw as per the slow one - out till its rough then back in slowly until its smooth.

Suggest before all this tho that you get it running with the cover off the carby and then give it a good squirt of carby cleaner first - it may just clear out any 'poop' thats there.

(Have faith even tho I have a Poulan with a carb that refuses to run on anything but carby cleaner. I have pulled it apart a few times and renewed all the perishable bits buts its a real pig)

Infocus in26 fan runs continually


Hello,
The fan does run continuously on this projector however it should be running very very slow when the projector has completed it's lamp cool down routine.
The reason for this is that a portion of the switching power supply remains energized (running) when the projector is at rest. But as I mentioned it should run very slow in this state. If it remains running full blast then most likely the fan speed control chip is shorted which can cause fail 2 ways, either the fan 1. runs full
speed or 2. remains stalled (then the projector will go over-temp and shut itself down) I hope this answers you question.

Cheers
