Probably belts. Does it come from the engine compartment? Does it go away when you accelerate, or does it just get worse?
bad tensioner, replace the belt tensioner/pulley. I had the same problem.
maybe its polyuria(a symptom of diabetes)
Fan belt slipping
miss fire , vaccum leaking , worse case dead cylinder
It can do far worse, such as destroy your engine block. I wouldn't worry about your heater core, I would worry about your Engine.
If the heater has a sweet smell it could be that the heater core is leaking engine coolant. When the leak gets worse you will have a wet floor on the passenger side and the windshield will fog up when you turn on the defroster.
No you should not because the dampness an coldness with Accelerate the cold virus an make it worse
replace or repair. It will only get worse.
I suspect a weak fuel pump. It will probably get worse; have it checked before it leaves you stranded.
A bad smell coming from the heater in a vehicle can indicate a bad heater core. One way to check this out is to see if the smell is worse when you sit in the passenger seat. If it is, there is a good chance the heater core is bad.
There is a good chance it's your drive belts. If it's worse when it's cold or when you start the car check your belts'
Get your engine belt replaced it is loose or worn.
Could be a bearing, could be a motor, could be something (like a sock) caught up in there...tough to say without opening her up!
I don't think so because when we have a cold, it is best to keep oneself warm and thus the heater produce heat for us to keep warm. Unless we have a lousy heater which produce cold air instead of heat, haha!
Running the AC compressor uses horsepower, and the truck does not have enough to overcome the loss.
Its a big issue you should call a water heater repair person to solve this issue. As after some time it will damage the water heater so you can call any professional plumber to solve this issue.
Found the problem. Rust on the pulleys. Wire brushed the rust off no more squeal.
more than likely a valve!
depending on how fast you accelerate, you get worse/better mpg a slow acceleration produces better mpg than a faster acceleration.
Frequent changes in daily schedule, inconsistency when addressing behaviors, physical punishment and some types of food such as gluten, casein etc. The list could go on and on.
Possibly front wheel bearings or the front brake caliper's or sticking on. My car is doin the same right now. I'm replacing the wheel bearings and front caliper's,pad's and rotor's.
Of course it affects the air conditioning,,,it also affects the heater. Any time u have a restricted air flow it affects how heater and air conditioning works, for the worse. Engineers have designed the heater/ac system to run on clean air, so therefore your heater/ac systems work faster and better with a clean filter. Not to mention your own physical health by breathing clean air.
There is a large amount of leaves or pine needles in the blower wheel. It most likely gets worse the higher the blower setting, the faster it spins...........
Worse is a comparative verb. As in bad, worse, worst.
