Question about 2003 Nissan Altima

1 Answer

2002 New VW Beetle is only blowing hot air out of vents even when set on cool. I was driving and I made a turn at an intersection and all of a sudden the cool vent air turned to hot air like I had the heat on. I tried to turn on the AC and even the AC blows nothing but hot air. Even while the vent is off the hot air still blows through. I took to a mechanic to because I thought my AC went out or something but he said the AC motor on the engine side is blowing cold air and is working perfect. The car isn't overheating either.

On the bottom of the air unit is the lever that changes temps. It likes to fall out of place.I propped mine back with a piece of half-inch copper pipe a couple of years ago.Remove glove box then panel on front side of console to access.

Ok, here is the scoop on this. if you sit in the passenger seat and reach under the dash in the center of the vehicle. So your laying in the passenger side of the vehicle and placing your right hand on the floor board were passengers feet would go, slightly to the left of there is where the carpet raises up to the center hump behind the button for emergency flashers. Ok there you will see or feel a plastic small arm attached to a wire rod. this plastic arm is most likely broke or like mine the its worn, so push it back inside the small hole, while turning the heat switch from cold to hot. All this little arm does is open and close the heat vent, but also allows the air conditioner to fully turn on. As you turn the heat switch you will see, or notice it catches the mechanism and the heat will switch on or the air will come on as you turn the switch. I had only a few minutes left to short fix this so I opted to glue the darn thing in place, yes a quick fix but its working and after only looking and poking around I now know what this is so when I have time i can fix it. My own mechanic whom I trusted for years said look its the heater box major repair. I know he doesn't care to work on Vw's its all good but it cost almost nothing to repair this badly designed item. I was ready to sell as is and take the hit but waited one more day when I could find my good flashlight and just refused to believe I had to take off the dash. So dont go to dealer unless you have the time and you point out whats wrong, they also said it was both the air compressor and a cracked heat box? find and locate it yourself I don't have a warranty on this 2002 1602,000 mile car, but I keep it running with good maintenance and all you who are kind enough to keep us all updated on your finds.

2002 Beetle Engine cuts out after it warms up for a few hours.


Hello,
my advise to you is that:
Your VW problem is the throttle body, (good news) it doesn't need replacement, it only needs to be cleaned out, and even better if a good technician (know what he is doing) can run an adaptation procedure.
this will restore the ZERO position for the TPS and relearn the target engine idle speed.
Good luck.
Note: you are in my prayer.

2002 vw beetle ac prob. was cooling one minute then i turned ac off for about 5min. when turned back on ac was blowing hot air.


Too much pressure build-up when you turn it off, the compressor will not function.
You may have "air bubbles" in the system.
Have refrigerant checked (for free) at most auto stores (call ahead).

Hope this helps!

2002 kia sportage temp gauge runs hot while driving


Cheak to see that the coolant fan is operating with the A/C turned on. The fan has to work to help the engine stay cool and help the A/C. When you apply heat on the control it acts to reduce the coolant temp. You will have to get the coolant fan operation checked. This can be :fan motor, fan relay, temp sensor and computer. Good luck
