Passat (B7) :: AC Take Longer To Start Blowing Cold Air


Jul 23, 2015

My 2013 Passat SEL TDI has 40,000 miles on the clock and in the past few months I've noticed it's taking longer to start blowing cold air. I've had several summers already so I'm already used to it's performance in the hot summer months but this summer has been different. The A/C will not blow any cold air at all before the car gets going under load (it didn't need engine load before) and sometimes it just won't blow cold at all but just barely "cool" air. I'll sometimes be driving for a half hour and never get the A/C to really blow cold.

Other times, it'll blow just fine. It's the hit and miss performance that has me confused. I then bought one of those refrigerant bottles from an auto parts store that comes with a gauge to see if maybe I have lost refrigerant or it's low but when I checked the gauge the pressure was exactly where it needed to be. I just came off that dreaded 40K service at the dealership and am trying to avoid going back there at all costs...

Camry :: 2007 XLE - AC Takes Longer To Start Blowing Cold Air

My car had some minor front end damage repaired by a body shop. Since I got it back the a/c takes longer to start blowing cold air. If I drive it daily the a/c starts up normally. But if the car sits for a few days, it may take anywhere from 3-5 minutes before it blows cold. I've taken it back to the body shop who has in turn taken it to a dealer and nothing was found.

Ford 6.0L Power Stroke Diesel :: AC No Longer Blowing Cold Air

Ac is no longer blowing cold air and was thinking about trying a can of ac pro on her. However, I have heard some pretty bad stories about people killing their compressors and overcharging the system. Is it not worth the risk.

Passat (B6) :: 2007 - AC Taking 10 Minutes To Start Blowing Cold Air

When I start the car after its been sitting for a few hours it takes at least 10 minutes to the ac to start blowing cold air. If it sits for less than an hour cold air comes out right away. Went to the dealer last summer and everything was working to spec, of course...

Passat (B5) :: A/C Isn't Blowing Cold Air

I have a 2004 Passat 1.8T and I am having issues with my a/c. it isn't blowing cold air. The first time it happened, I paid to have it recharged and it worked for 2 weeks then it went on the fritz again. I had the gas pressure checked and it is at a regular level. The second cooling fan comes on when the a/c is turned on, the fuse and the relay are also good. I checked the a/c pressure sensor and it is also working properly. I suspect that there is a valve or sensor that has seized up (due to the temporary addition of refrigerant). I also scanned the HVAC for fault codes and the only fault is an air flap position motor.

Ford A/C :: Taking Longer And Longer To Start Cooling?

02 Ranger 2.3 4cyl 5 spd 115K.... My A/C seems to take longer and longer to start cooling/ When it does start cooling it seems that is is actually colder than it has ever been (original owner) and the control is more sensitive to the touch when moved. Being a 4 cyl it's easy to detect when the compressor kicks in and it seems each time it is taking longer to do so. If I stop the motor, it goes thru the same cycle of time or longer before cooling (compressor kicking in) again. No codes, No unusual noises.

Passat (B6) :: 2008 3.6 Engine Requires Cranking Much Longer To Start

What updates were done to the 3.6 engine for 2008? So far in 100 or so miles I've noticed that the 2008 3.6 is:

Much easier to start. (06/07 requires cranking much longer to start)
idles smoother (06/07 shook a little when sitting at idle)
accelerates smoother
then the 2007.5 3.6 I had, and the 2006 3.6 in my friends Passat.

Both of those did have the OJ update done. The only visual difference is the plastic engine cover. On the 06 and 07 it has a silver colored cover. the 08 has a black cover that is different in shape.

Passat (B5) :: 2000 V6 Heater Vents Blowing Cold

I took my 2000 V6 Passat into the shop because my heater vents were blowing cold. They tested the system and told me the following:

The hoses leading to the heating core are warm, but no warm air is leaving the heater core, indicating that it's plugged up with corrosion. They testing the coolant fluid and found that the incorrect coolant had been put into the system and that the fluid was carrying an electrical charge that must be corroding the aluminum portions of the system. In addition, the engine temp sensor is kaput and never goes up.

They offered a garden hose flush the heating system for a few hundred bucks, but warned that it is only 50% successful. They recommend replacing the heating core.

Passat (B6) :: 2006 - AC Stopped Blowing Cold / Compressor Is Always Engaged

The A/c stopped blowing cold on my 06 Passat 2.0t. I checked the pressures on the low side of the system and it was 100 psi with a cold engine and 130 when hot. Obviously this is too much. It seems as if the compressor is always engaged even when the a/c is off (every part of the a/c pulley is always spinning the little nut sticking out of the center of the pulley spins as well not but im not sure if that's how it is when the compressor isn't engaged).

Passat (B5) :: 2002 V6 - No Heat / Cold Air Blowing At Idle And Under Load

2002 Passat v6 - climatronic control...

I have just cold air blowing at idle and under load. I have read posts and checked the following: temp remains at 190, heater coil hoses-both are hot and removed the dash to see if the flapper door (red arm) was moving-it is. Any other things I can check?

Passat (B5) :: 2003 V6 AC Blows Hard But Quit Blowing Cold

Have 2003 V6 FWD Passat. A/C blows hard but quit blowing cold. Noticed last week, that sitting for a long light, A/C would quit blowing cold, then cycle on again every 20-30 sec. After worked fine. Yesterday no cold air.

Read on forums about the 384 relay. My electric fan is NOT coming on. Started car, turned A/C on high, and checked voltage on connecter to fan. was negligible. Car was fully warmed up, so i figure voltage should be 14.0 VDC

Making assumption that it is either the AC relay 384, or the fan relay but there are two, a 214 and a 213.

Passat - Volkswagen :: 2002 - Only Cold Air Blowing When It Is Supposed To Be Heat

I have a 2002 Passat that is only blowing cold air when it is supposed to be heat. I have checked the following items:

1. Both heater hoses are hot at the heater core which would indicate that the core is not restricted.
2. Air has been bled at the heater core and the antifreeze is at the correct level.
3. Car thermostat is operating correctly and maintains a steady 190 to 195 degrees.
4. When temperature control lever is moved from "cold" to "hot" the air noise definitely changes like a damper is moving but there is no change in air temperature. This is a manual control with cables (not digital read-out).

From what I have read so far I am convinced that there is a problem with the blend door but referring you back to #4 (air noise change) I believe that the cable is moving the damper. Can the blend door be accessed on this car without removing the center console? Can it be accessed through the glove box area?

Ford Super Duty (1999-2016) :: Start Blowing Cold Air - Motor?

Here's what's happening:

I can have it on hot and be driving along, then it will start blowing cold air. I can move the temperature switch to cold then back to hot, and it'll start blowing hot air again.

Need to know if that would be temp or the motor? I don't want to just change parts randomly.

Ford Ranger / B-Series :: 2003 - A/C Start Working Properly And Blowing Cold Air

I have an 03 Ford Ranger 4x4. Great truck and runs great just with one small problem. For whatever reason, every single time, the a/c only blows un-cool air (not hot) when I start the truck. Then, and only then, after about 30-40 mins of constant driving around does the a/c start working properly and blowing COLD air. After that it works great but it always takes about 30 mins after I start the truck for it to work correctly.

Ford A/C :: 2000 F250 Start Blowing Warm And Slightly Humid Air Then Suddenly Cold Air Come Back

I just bought a 2000 f250 diesel truck and am having problems with the ac. When I first turn on the ac it blows very cold and works perfectly but after about 5 or 10 minutes it will start blowing warm and slightly humid air for probably around 5 or 10 minutes and then suddenly the very cold air will come back. This cycle repeats over and over again and I'm not sure what is wrong.

1998 Ford Mondeo - Air Conditioner No Longer Blowing Out Of Front Vents

1998 Ford Mondeo. Yesturday I changed my air filter and went for a drive today and realized, that air is only coming through the vents right under the windscreen. I am pretty much car literate but cant afford a mechanic...  Research I've done (on the net) shows the problem has something to do with the aircon no longer blowing out of my front vents where the A/C is supposed to blow out of, instead it was blowing out of the defrost vents along the windshield. The air will blow high, med, low, cold warm, ect just only through the vents near the wind shield. It has something to do with the vacume?? and the firewall...??? Apparently??

Where to start to get my aircon working again.. Pretty positive I installed and reset the fitting for the air filter correctly. I had my bonnet up so it can cool and I could change the filter and the wind blew it down, and may have something to do with it, I cant see any damage though..

Ford 6.0L Power Stroke Diesel :: Longer Crank While Cold?

It's -15f today. I have been wanting to make a cold start video for a while. Today seemed like a great day to make one.

A little longer crank than when i plug it in, but I think it started pretty good.
