SOURCE: SMELL IN SIDE THE CAR FROM AC

There's no cabin air filter on your vehicle. What happens is dust, lint or so-on gets trapped in the evaporator core for the a/c and starts to stink over time. Ask your local parts store for a de-oderizor spray for your a/c.

SOURCE: When I turn on the AC a moggy smell blows out of the vents.

mould in evaporator case?
some vehicles have a pollen filter(air conditioning air intake filter)not sure if your vehicle has but check if it has, may need replacing.
check plenum chamber(area under front windscreen)for leaves and debris.
then can try and spray mould killing pressure can(glen 20)air freshner in through intake air places under front windscreen with windows down air cond on full fan speed on fresh air while engine running or not depending on how long and how bad smell is.
may also pay to check for blocked air cond. drain tube, is it dripping water when running?
service centres or hire places have also got fragrance and mould killing machines you can use inside vehicle under similar conditions as above(ozoneator)

AC blinking is the self diagnostic system of the AC unit. A pro needs to repair this.

You most likely have leaves or a field mouse nest in the ducting and they are smoking when they get on the AC blower motor speed control resistor it is very hot. You can start a fire so have the blower motor removed and the leaves and or mouse nests cleaned out.

2006 Toyota Sequoia AC light on dash stays on and AUTO button seems stuck. Did what the manual said to do and it did not work. How do I get the auto button off and is it going to burn out my AC compr

That won't burn out the compressor. It could be dead already. There are several things that will keep the light on, in the dash. High, low pressure switches, A/C .heater controller malfunction, wiring, and the compressor is bad. All these turn the light on, but all will shut down the system. Put it on a scanner and find out what's wrong.

What is causing water to leak down onto the passenger side floorboard of my 2004 Mazda 6 wagon when I have AC on?

Feel the water and smell it. If it smells sweet and fells oily, is is coolant. If is isn't oily and has no real smell, it is water. There is a tray under the evaporator and heater cores that catches water/coolant and drains it via a tube thru the firewall to the outside of the car. This tube is probably clogged and needs purged. If you have coolant on the floor, you'll need to replace the heater core. If it is water, purging the hose will solve the problem as the water is just condensation from the AC coils

2004 Toyota Sequoia AC Light Blinking

when you fit a compressor . after vacuuming the system for about an hour, you connect the gas up to the suction port and let the gas in
with the engine running and the ac switched on , when there is enough in the system the low pressure switch is turned on and the compressor starts to run sucking in more gas
The system is charged according to pressure gauges and not by the number of cans
now you are doing several things wrong
1-- there are 2 types of gas and if you used a wrong replacement unit , it will not handle the high pressures of the different gas
2-- if you used the no of cans method -- then liquid freon gets to the pistons in the compressor and hydraulic locks the system resulting in the destruction you describe
3--- did you put oil in the compressor before fitting it
as the oil circulates with the gas and there was no oil i the replacement compressor , then the plate runs dry and seizes , again causing destruction
the best method is to get an accredited ac professional to do the job or it will cost you more money

AC blows hot air out the front vents no matter the setting. It is winter so it is not too bad. The back vents blow cool air but not cold.

Getting your system recharged at a dealership would be recommended but only hot air coming through the front could be an hvac problem, make sure that all your vacuum lines that run to your system are not crushed or unplugged, they will be located in the engine bay of your vehicle.

AC flashing light in Sequoia and no cold air!!

The Sequoia's A.C. is forever a problem,taking to the dealer and spending a few grand is just a temporary fix,and since it's not a driving issue,there is no recall,found a site where a heap of Sequoia owner's all have the same problem as your's,I bought A 2004 Tundra new and sold it a couple of years ago,only had 68,000 miles and had no A.C. issues,so it's only a Sequoia issue,I would sell it instead of sinking a bunch of money into it and it still be problematic.

When i turn on the AC it only blows out hot air and something underneath the glvoe compartment makes a ticking noise what could it be?

open the hood and check the sight glass for bubbles with the ac on if there are non then you probably have a hole in the ac system as for the ticking noise it could be something stuck in the blower motor or a bad bearing
