Golf IV / Jetta IV :: A/C Not Working Properly - Fix?


May 30, 2016

Heat blows warm at best and A/C isn't all that cold. I want to believe its a blend door issue and dive into it this weekend and fix it but there isn't a single piece of foam coming out of any of the vents. Of all the systems on the car HVAC isn't my cup of tea I don't know anything about it. What else could be the problem?I can live without A/C but the heat things must be fixed.

Golf IV / Jetta IV :: 2001 - Cooling Fan Not Working Properly

I am having issues with our 2001 vw jetta wolfsburg edition with a AWW engine the cooling fans not working properly. I had a bad fan and replaced it and since changed the thermo fan switch and the module under the battery and still no luck. With the key off I can jump the fans via the plug for the fan switch only low speed works with the key off. with the key on i can get both speeds of the fan to operate. With the ac on the fans operate.. normal driving the fans will not operate. and the engine will overheat and fans will not go on. Any other relays or sensors that could be faulty?

Golf IV / Jetta IV :: 2001 - 4th And 5th Gear Won't Working Properly / Deceleration And RMPs Drops

My problem(s) are as follows:

I recently got a 2001 VW Golf 1.8T from a buddy in the Marines. He delivered it to me at my home almost 4 hours away, as described, reportedly without any issues. I got all of the paperwork transferred so that my wife could have a solid daily driver, only to discover ...

1) The vehicle in question was apparently used by a car audio company local to him, who has done some serious screwing with the electrical system in order to incorporate (and then remove) their crap.

2) When shifting through the gears, and coming to 4th gear, you get a couple of seconds of initial acceleration, followed by deceleration and RPMs falling, which in turn leads to the speedo dropping.

3) The same thing happens in 5th gear.

4) The only option is to downshift to a lower gear, which she did, and was apparently cruising along at 60 mph in 2nd gear, as 3rd gear was behaving the same way as 4th/5th upon downshifting. I'm not a mechanic by any means, but I'm pretty sure this is a BAD thing .

Golf/GTI VII :: HID Low Beam Not Working Properly?

I had some Helix HID lights installed (opdparts). The lights all work except the driver side low beam. Here are two short vids showing problem:

The light in question also will flicker if I hit a bump. I tried to research solution but i'm ignorant on this matter.

Also The adjustments do work for the light. I can raise/lower or make beam go left or right.

Golf IV R32 :: Rain Sensor Won't Working Properly?

So far i haven't been able to find a lot of solid info on this rain sensor. Here's what i know:

My sensor indeed works, if i remove it and move my fingers the wipers will speed up/slow down accordingly. It looks like the window has been replaced and a very "shotty" job was done replacing the sensor/rearview mirror.

There was extra adhesive around the sensor, i removed that and cleaned it up, also cleaned up the gel over the sensor. Reinstalled everything, still cannot get it to work.

If i have just the sensor on the windshield, it semi-works, but when i put the mirror back on, it doesnt work at all.

I know the sensor is good, i get the fastest wiper settings. Relay #192 is good.

My best guess:The sensor is going bad, or the gel isn't making a good enough contact with the windshield allowing it to "detect" the rain hitting it. You can tell the gel isn't in the best of shape and I am pretty sure that's the culprit.

Where to locate a rain sensor? or the Gel, or if any gel can be used, I am going to try and find something i can "substitute" in place of the gel thats on it.

Golf IV R32 :: Outer Door Handles Not Working Properly

Ever since I painted my car my outer door handles have not worked properly. Once you open the door using the inner door handle then the outer one works fine...lock the doors and the outer handle becomes almost useless. I say almost useless because if you kind of pull it just right it seems to catch and work. How to remedy it? Really tired of using this auto window roll down to reach in and open the door.

Golf IV / Jetta IV :: 09a Transmission - No Reverse / Car Doesn't Shift From 1st To Second Properly

Bought a 2003 golf gti 1.8t as kind of a project. Car had no interior no exhaust and some shifting issues. To fix the shifting issues rather than replacing solenoids I just got a rebuilt valve body. After installation the car still doesn't shift from 1st to second properly and now I don't have reverse. (It's an 09a transmission)

Golf IV / Jetta IV :: 2005 - Car Would Not Accelerate Properly From A Standing Start

Crank position sensor was replaced a few months ago. After that noticed that it would not accelerate properly from a standing start. No jerking or anything, but way back it used to be able to spin the front tires a bit, but now not getting that needed acceleration. After hitting 15 or 20 mph, then it's back to normal and road and highway speeds are nice with power.

The reason the crank position sensor was replace was on account of intermittent no starts. That's gone away, but now this acceleration problem. Could it be a leaking air from the outside into the intercooler? Would a VAGCOMM show what's going on? Golf TDI 2005...

Touareg :: Nav System Isn't Working Properly

I have had my T-Reg for 2 weeks now, and absolutely love it! However, there are some strange things I have found with the Nav System that are just a bit annoying.

1) Not all cities are on the CD. This is obvious - they can't put *all* the cities on, but there has been more than one occassion where the city I needed was not in there. For instance, I tried to find "Centerville, VA" but the Nav System only knew "Clifton, VA" (I guess they are the same), which ultimately became "Fairfax, VA." I didn't realize it was "Clifton" until I arrived there (following a map) and saw a sign.

2) There are two sections of major roads that I travel (Rte. 95 and Rte. 66) where the Nav system stops giving me directions to my destination. It tracks my position on the map as I am driving, so I know I have a fix on at least 3 satellites, but when I press the "i" button for my next cue, it says something like "Routing to your destination is not available from this location." The blue line on the display that shows where I should be going also is missing. Once I exit either of these major roads (in the areas that this occurs) the Nav System resumes guidance.

3) The map display on the Nav System is always "behind" by 10 or 15 seconds. When I cross a roadway, the map doesn't indicate my crossing until a good 10 or 15 seconds later, depending on my speed. The turn-by-turn display and voice prompts are *dead on*, it is just the map that isn't.

Golf IV / Jetta IV :: Gas Pedal Not Working On VW GTI VR6

Today I pulled off the front bumper assembly to install an oil pressure gauge. The wire that goes from the sender to the gauge I pulled through A rubber boot that had a cluster of wires located next to the driver side windshield wiper, I pulled the wire through with a coathanger or I could've scratched another wire which is causing the gas pedal not to work? Or could it be when I pulled off the bumper assembly something unplugged or broke? VW GTI VR6.......

Golf IV / Jetta IV :: Keyfob Won't Working?

After a long day at disney, we walked to the car, and couldn't remember where we parked. I kept pushing the panic button looking for the car (I read pressing buttons too many times out of range can cause it to un-sync from the car, might not be true though?). Well now my keyfob won't do anything except start the car. I normally wouldn't care at all but I can't lock my driver door.

For some reason my key won't turn right to lock the door, and will only turn left to unlock (not sure if that's just how it's supposed to be). I tried something that I was pointed to in a thread on here [URL].... but could not get it to work. I don't have 2 keyfobs, just one and a valet key. I put a brand in battery in the key hoping that would work, but still nothing. I don't live in the best area and I'm desperately trying to find a way to lock my door without having to go to a dealership and shell out a bunch of money.

Passat (B5) :: Secondary Air Pump Won't Working Properly

I have had an engine code for some time claiming my auxiliary air pump is not working properly. My indy saw no obvious problem, but it could just be shot. He suggested I take it to the dealer. But from my understanding, that pump only works to achieve cleaner combustion when the engine is cold right after a start. I am tempted to continue ignoring it. Would I be making a mistake? I haven't noticed any power or mpg reduction.

I guess I can always take my car in for the under the hood seal recall and have them do a diagnostics too.

Prius (2010-12) :: IPA Not Working Properly After Repair

Well, just a little history of what'd happened to my Prius 1 month ago; I've got rear-ended and was shunted forward and hit the car in front of me, so the damages were both bumpers at back (more severe) and front (slight damage to the front number plate). Got it back last Thursday and it all looked fine and well, until today where I was being asked to show off the IPA at work, and it is not working properly, in fact it is not working at all.

GTI 337/20th Anniversary :: Transmission Won't Working Properly

Today I was driving getting on the highway while having the clutch engaged I went to shift into third and it was very hard to get it into gear. For the rest of the day today this was a problem and especially at higher rpm. I am pretty sure my clutch is going. I asked around local and they say it is the clutch. Do I need to also replace my flywheel or can I just use my old one?

Volvo - S60 :: AC Not Working Properly / No Cool Air After 20 - 30 Minutes

When I first get into my car, the AC works and the fan will move the air. However, after 20-30 min., the air is no longer cooling and I can barely feel the fan blowing the air and I have touched neither the thermostat control nor the fan. The AC will not put out cool/cold air with the fan at the same position until after the car has been turned off for at least 10 min.

Golf IV / Jetta IV :: Wipers Not Working - ABS Light On

About a week ago I turned on the Climatronic a/c in my 99.5 GTI for the first time since I bought the car. Everything worked fine until a bug splattered my windshield. I sprayed washer fluid and the wiper moved extremely slowly to the halfway point and then stopped. The wipers have always moved slowly since I got it about 6 or 7k km ago but have never become stuck. I turned off the a/c and let the car sit for a while turned off. When I turned it on again, the wipers worked fine but the were noticeably slower then before.

Cut to a few days later, I turn on the wipers to test it out and it gets stuck again, this time about 3 inches from the bottom. I can hear them clicking as if they are restarting the cycle, but it only twitches.

Cut to now, the wipers try to move every time I turn the key to ACC, as well as twitching when the car starts. When I start driving, after approx. 2 minutes my ABS light comes on and doesn't go away until I shut off the car.

I have provided a video. This is my only car and there's rain coming up in the forecast ...
