There is a automatic fan speed control module, it sounds like that may be your problem.

Hello...I have a 2009 chevy cruze 1.8L ,some 3 months ago,the car had some pulsating and vibration during driving , so I changed the spark plugs and the problem was solved, but after about a month,the car...


Was any of the previous spark plugs fouled? Dirty? If so you need to investigate whether the problem is oil or fuel causing the fouling. Also a possibility is that you have a bad plug wire and when you changed plugs you disrupted the plug wire enough to make contact. Now possibly the plug wire is showing too much resistance causing a misfire at idle. Only way to be sure is to have the car scoped to see if the wires are proper or defective. That is unless you are the change parts and try type. In that case try a new set of wires. The reason is because at idle the voltage is not as high as it would be at higher rpm.

I recently put new front brake pads and had rotors turned on the front end of my 2003 tundra sr5,after a month of driving i'm getting the pulsation when braking back which is why i made this repai


HI if you have pulsation after a month you must replace the rotors
they are too thin and the heat is warping them faster then before you
had them turned
note you replace brake pads and rotors

good luck

I have 2002 silverado, the brake pedal pulsates and pushes back as the vehicle is slowing to a stop.I replaced the pads and rotors and the p loblem still exists. I now believe this isABS related.


Hello. What you are experiencing with the pulsating brakes and the brake pedal pushing back is the antilock brake system [ABS] working correctly. Joe

Brakes pulsate when stopping vehicle but I have 70% front brakes and 40% back brakes left.


Your brake rotors may be warped, which causes the pulsating you are experiencing. It's ok to drive it like this (although annoying), so if it is driving you crazy, you can have the rotors 'turned' (ground down to eliminate any high spots) or just replace them with new rotors. An automotive shop/parts store needs to measure the thickness of the rotors to determine if the rotors are thick enough to allow them to be turned. Check the price on new ones anyway, as sometimes the price difference is minimal.

PULSATION WHEN APPLY BRAKES


Even though you replaced the rotors, seems that you will still need to have them resurfaced. This assuming you are experiencing pulsation only when braking.

Brakes pulsate real hard


That is just the ABS system at work. It is supposed to prevent your wheels from locking which often makes the brake pulsate, especially in wet weather or or snow or ice. The only way to really stop this is to disable to ABS by unplugging it and removing the fuse. This will make the ABS light appear in your dash, but your brakes will stop pulsating.

Brake pad pulsating


Possible causes- low spot on the rotors. Caliper pins not sliding with pulsation. May not need to replace pads.
