Question about 2002 Toyota Highlander

Open Question

Ac blowing hot air, but also rattles

I was told I need a new compressor because of the rattle (piston related) is what the mechanic told me. Is this correct? I see lots of people have been told it's to replace the compressor when that isn't the problem.

    is the rattle coming from under the hood or in dash area? If its under the hood then more than likely is the compressor. If its in your dash area its not the compressor.

SOURCE: front suspension noises, bad new struts?

It sounds like the mechanic may have left the upper strut nut a bit loose, you may want to ask him to check it, but be nice, Toyota had some problems with upper strut mounts. These are on the top of the strut, they hold them to the body of the car. Unfortunately you have to remove and disassemble the struts to replace them. You could try asking your mechanic to just replace the one side and try it. I'm pretty sure that's your problem and he may give you a break since he's done all the other work. There is also a bulletin on a rattle from the side view mirror, but I think since this just started with the strut job, the mount is your most likely cause.

check your air gap on the compressor pulley where the clutch and pulley meet. you should be able to fit a postcard in between it. if thats good then check your tensioner. there should be lines on it to tell if its wore out

SOURCE: car rattles under right side of dash when accelerating

The rattling sound coming from the a/c system may be a sign of a failing blower, or there might be an object hitting the blades.

This can be inspected by an a/c technician, or if you are patient enough, you can check it yourself. Many automotive a/c blowers are located behind your vehicle's dashboard glove box.

Hope this helps.

Why is there a rattling sound under my hood after i re charged my ac?

The possible problem here is that you put in too much gas and the compressor pistons are pumping liquid and not gas . This is hammering the rod ends on the swivel plate and if allowed to continue will result in compressor failure requiring a new compressor Have an accredited ac specialist shop check the pressures in the system and adjust to correct levels.

I have a 2000 Dodge Intrepid r/t my air worked

I am sorry for you, as it is becoming more apparent that an increasing number of Technicians, should be with Kermit, on the Muppet Show, and not charging fees for **** workmanship.
I have written this down on FIXYA as many times as I have had a Hot Dinner this year.
When at a Shop, for A/c for example, always ask for a CHECK AND ADVISE.
Yes, you pay the FEE for that, but you should get a Full Written report of the Findings, by the Technician.
Such as High and Low Pressure readings from the Run UP Test, and if the readings are Out of Parameter for the system, the apparent Failure[s] in the system, Compressor, Low Freon, Plugged Filter Drier/Accummulator, Ctuch and /or Pulley etc.
Tolerate the inconvenience, and go back and ask them what did they exactly do, if it is not already clearly notified on your Invoice.
Should you get fobbed off, rattle their cage with a Better Business/ Trading Standards threat to complain.
Come back to me, if you are dumped.

A/C Problem Tensioner rattling

well if it is the engine i am thinking of that has the small ac belt with the little tensioner on the passenger side bottom area it is most likely the ac clutch is locking up turn the rear air of have some one rev the motor watch the tensioner if it is moving alot banging into another part making the rattle then you might get ready to have to replace the compressor when it gets worse they usually break the tensioner.

Heating/Cooling System

compressor pump is shot. there are pistons with seals inside the compressor if u don't regularlly use the ac the seal could go bad. rifrigerent r134 is the current standerd now for ac refrigerents u may have to do a retro fit it since that made tis maditory damit I can't remember but ne way. The refrigerent is compressed and pushed through a condenser as well as pipes and orfice tubes . when compressed the gas gets cold ,kind of like the oppisite of a dessel engine, they use compression to ignite the dessel rather then a spark plug

1999 Pontiac Sunfire AC problem

Check to see if your system is charged. there is a pressure plug with a green cap near the right side motor mount. If you have pressure then check fuze under hood and see if compressor is kicking in. If not charged it will not kick in.
