Question about Cars & Trucks

1 Answer

2004 accord v6 A/C is not working blows hot air only. Replaced both fuse and relay. The a/c clutch does not engage when you turn on the a/c. But it has came on twice when I turned the car on in the morning but as soon as I drive off I stops. Weeks before it stoped completely stoped working I was parked for about 15 min with a/c on and it suddenly started blowing hot air and you can smell the change too. I drove the car around the block and it worked fine . Car a/c worked great until it failed 3 weeks later. Any ideas ? Thanks

There is a high and low safety switch on the system. When the pressure goes either way too much it stops the compressor.

The problem might be that you got out of freon gas.

It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.

Air conditioner blows hot but freon is full


Your compressor could be faulty. Check to see if it engages when you press the AC button with the car running.

Air conditioning problem

Ac is not blowing out cold air. You have to put gages on the system and it shows its has freon.Checked all fuses and relays. The two fans in engingine compartment do not come on when the ac is turned on but does when the engine gets hot. The compressor engages when turned on also.
If the magnetic clutch engages the compressor and still no cold air could be still low in freon or the HVAC unit.

Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?

My AC is not blowing cool air. Compressor clutch is not getting engaged. AC button is showing green light indicator though. I am suspecting clutch relay problem. where is air conditioning clutch relay in...


First of all check the freon pressure, if the pressure is low the compressor clutch will not turn on. The pressure should be between 30-40 PSI.

AC blowing hot air, and won't accept freeon (2004 silverado Z71)


You may have already done this but thought I would throw it out there. Have you checked the fuse for the A/C compressor or the A/C compressor relay? If not just to let you know they are both located in the underhood fuse panel (below is a picture of it). Also below is a siagram of the fuse layout. The fuse with the yellow arrow is the fuse for the compressor and the red arrow is the A/C compressor relay. onther possible things could be a bad pressure switch. Do you have any pressure in there at all? Just a couple of things to check out. I hope this helps and good luck.

Air conditioner has freon but it only blows hot air


Sounds like the A/C Compressor Clutch isn't engaging. With the A/C turned on and the engine running, open the hood and see if the center of the A/C Compressor pulley is rotating. If it isn't, then that's why there isn't any cold air. Check all the fuses and relays then check to make sure that the A/C Compressor signal wire is getting 12V when the A/C is switched on. If the compressor clutch isn't engaging, the fuses and relays are good and the signal wire to the compressor is getting 12V then the A/C Compressor itself may need to be replaced. This is, of course, assuming your are certain that there is refrigerant in the system and it is at the correct pressure!

When i turn the a/c on it blows the a/c clutch fuse


The ac compressor is probably siezed. When you're turning on the ac it cant turn the compressor so its blowing the fuse. It could also be that the clutch windings are shorted.

That would be my first guess.

You can locate the wires on the compressor clutch that engage the clutch, remove the belt, and leave the engine turned off. Apply power from the battery to the clutch wires and see if you can move it at all with your hands. Use small gauge wire and maybe put in a inline fuse. If the clutch is burned up it will blow the fuse. I think the inline fuses are pretty cheap at a auto parts store. If its not burned up, and you cant move the pulley at all by hand, more likely than not you need to replace the compressor.
