Do I have to pull out the complete switch assembly, or could it be some thing else?

Silverado :: 1992 Chevy 1500 Runs And Starts Great But Won't Do High RPMs
I have a 92 chevy pick up 5.7 with 159,000 miles. The truck runs and starts great but shortly after I bought it 3 years ago it developed a sort of misfire at higher rpm's, it's fine if I drive it normally but if I try to pass someone it will downshift then fall on it's face, (spit,sputter and slow down). some times I can feather the accelerator and it will come back again. I normally don't drive the truck in the winter but this week I was forced to use it and the cold weather is seriously affecting it, it took forever to get it up to 70 mph after getting on the highway. once up to speed it will do 75 all day without an issue.
I've replaced the plugs, wires, pulled the throttle body and cleaned it as the port for the pcv valve was plugged solid with carbon. I have not replaced the cap and rotor as they seemed to look fine. I have not checked the fuel pressure because it will break the tires loose upon take off and I don't think that would be possible if the pressure was low, would it?
Sonata NF (2006-10) :: Blower Motor Vibration (heater On High)
Went to have an oil change....service rep came in with my cabin air filter and said it needed to be replaced, I told him "later" as they charge too much for a simple filter.
Two days later I had the need to run my blower on high and it vibrated rather loudly.. I tried different positions on the vent switch but nothing worked.. then it came to mind the Jiffy lube incident. I went in and pulled the cabin air filter out and saw nothing wrong there. Upon further inspection I found a piece of an acorn in the blower wheel.
Moral of this story...if you changes cabin air filter, be sure to check for any debris that may fall off the old filter into the blower wheel when it is removed.
Ford A/C :: Heater Fan Only Operate On High Speed
Just replaced my heater resistor as the fan would only operate on high speed. Now I have the fan blowing in all positions however there only appears to be 3 speeds Is that correct even though there are 4 positions. One speed at LO a higher speed on the next 2 positions (sounds the same) and then the highest speed on HI. Need to confirm if this is correct or could I have a faulty resistor.

I have a 2000 f-150 4x4 that has only high fan speed for a/c heater. Speeds 1-2-3- no longer exist. Is it a switch or a control module? Also, the door code for the rear differential is 19; is that limited slip?

So I used my 2000 silverado 1500 to remove a willow trunk from my yard. 4 Lo, took a bit of work but I tried not to overdo it. Now, truck sputters when accelerating. Once it gets going it's good but the startup is sputtery and bucks a little. What did I do?

View 3 RepliesFord Ranger / B-Series :: Fan Only Work At High Speed / Blower Motor Hose?
I recently bought a 96 ranger.I noticed the fan did not work but for high. I search the internet and found how to remove it and discovered a mouse nest(village) which basically took over the housing where the evaportor core,blower motor resides. I bought a chilton but cannot remove the housing around the core so I cleaned it the best I could(air compressor and vacuum and disinfectant)...
I had to buy a new blower motor and resistor. However, I cannot find the hose that attached to the blower motor?-mouse had chewed a hole in the one- I've looked and found serveral differents names for it but seems I cannot find it at my local parts store.
My question is- is this intake hose? vent hose? I'm guessing I will have to go to dealer or, if I know the name I can look it up in a salvage yard?
Ford F-150 (2009-2014) :: Blower Motor Resistor Replaced - Fan Completely Shuts Down On High Speed
I replaced the blower motor resistor on a 2010 F150 with dual climate control where the blower was stuck on high.
After replacing the resistor, now the lower speeds work fine, but when placed on high speed, the fan completely shuts down. Replace with the old resistor, and it only runs on high.
How to proceed, or what else might be the problem?
Dodge - Engines - Ram - 1500 - Blower-motors :: Air Conditioning Only Works When Driving Forward?
2005 Dodge Ram 1500 SLT Big Horn, 5.8L V8 Hemi my air conditioning only works when I'm driving forward, and does not work at all any more when I'm sitting still at an idle. this is a new problem. the A/C has worked like a champ for the past year (since I started using this vehicle). I even refilled it by myself last summer, with no issues until now. when it is at idle, I hear a clicking coming from the A/C system, and the RPM's arch a little bit. then it clicks again, and the RPM's go back down. it does this 2-3 times a minute. also when at idle, the air is VERY HOT, considerably warmer than the outside air. also, I have a pressure gauge for the A/C system (came with the refill kit last summer) and it says that the system is holding too much pressure. it suggests a possible mechanical problem.

My plan to clean the fuel injectors on my 2008 Silverado LS 4.8L V8 came to an abrupt halt when I was unable to disable the fuel pump relay because it is missing from the spot where it should be located according to the schematic in the owner's manual. Would removing the "fuel system control module" (fuse #21) instead of the fuel pump relay work?

I've got a "new" Blazer -95 4.3 vin W about a month ago. It has run about 170,000 km.
But now it looks like it was a bad buy, it runs bad. The rpm starts jumping between 1500 - 2500. Suddenly the break and ABS warning lights in dashboard lights up, and sometimes all black out and it stalls.
At first it started acting like this when towing a trailer on the highway, doing 80 km/h. But now it does it at any speed.
Engines - Failure - Cadillac - Deville - Fans :: 1996 - Replacing Fan Motor Causes Mph Sensor To Fail?
I have a 96 Cadillac Deville Sedan. Last year, I had problems with the heat and A/C working intermittently. Then both crapped out. I went the summer without A/C...waiting for winter. Have gone all winter with no heat, which is not a huge problem, since I live in Florida. However, I'm planning on taking this car on a 1600 mile journey to Maine. So on Thursday, my bf installed a new HVAC fan motor. Or, yeah, whatever you call them. It worked and the car produced heat. I had a parade to go to Thursday night, so I drove the car there and it was fine. On my way home, the car was revving, like I was driving a lawn mower. Then, while I was still driving at a low speed, the mph went to 0. During the 10 mile drive home, which included interstate, the mph returned and the car acted normal. Then the mph went to 0 again. The speed sensor failure light came on, along with the check engine light.
I thought maybe while replacing the fan motor, the bf might have unhooked the speed sensor. This makes sense to me. But the bf checks and can't find anything obvious.
Today, when I first start driving the car, it again sounds like a lawnmower. The rmp is into the 3000 and 4000 range, while I am driving (approx) 15 mph. If I step on the gas, the car lurches forward, then returns to lawnmower status. The mph is showing 0. The instant mpg is also remaining at 0. The fuel range is showing numbers, but they are not correct, since there are 14 gals of gas in the car and the range is at like 85 miles and declining. I get around 20 mpg. So that's not an accurate range. After a few miles, the car stops over-revving and sounds normal. On the interstate entrance ramp, the mph started working, and worked for several minutes, then reverted back to 0.
So, to summarize. The check engine light is on all the time. The speed sensor failure light comes on in the beginning. The struggling lawnmower act lasts for the first few miles. Lurching if I step on the gas. Then, it might drive normally. The mph stays at 0. Every once in a while, the mph will start working, then stop again. What could have happened during this fan motor repair to have caused this? Or is this just a huge coincidence?

View 12 RepliesCavalier - Engines :: 2002 - While A/C Is On Idles Widely - Constant Speed If A/C Turned Off
I have a 2002 Chevrolet Cavalier that recently is having a/c and engine problems.One problem is that when the a/c is on the car will idle very badly- possibly varying 300-400 RPM. It will do this until the air is turned off or it is given more gas.The second problem is when trying to keep the car at a constant speed with the a/c on the car will vary 200-300 RPM until the a/c is turned off or it is given more gas.The last problem is when the a/c is on and no more gas is given to the car the a/c will start to blow out hot air. However, when gas is given to the car (probably has to be at about 1500 RPM) the a/c will blow out cold air. The car is a 2.2L 4 cylinder. The car has had the check engine light on in the pass but I had cleared it (it was the o2 sensor) several times. But recently it has not been coming back on. I don't know if this has anything to do with it, considering it only happens with the a/c on, but I thought that I would mention it. The car runs fine without the a/c on (idles well and drives good at constant speeds).
