I have a volks wagon 1996 a code came up p1308 what is that


On some brands it involves the throttle position sensor, and on others it involves the air cond compressor.
I don't show that code on the list for Volkswagen models.

Air cond. don't leak onto the ground


If you mean the condensation water from the a/c - the drain tube is probably gunked up.
There is a small tube or hose near the passenger floorboard that the water drains thru. You should be able to see if from under the truck.

My chevy 2006 silverrodo air cond wont work on number five


without being able to trouble shoot the switch i don't have a solid answer for you but I would guess that the resistor in the switch burned out and a new fan switch should take care of the problem. good luch

2001 chevy silverado heater /a/c blower is working in all speed positions , but not any volume of air out the vents


check your owners manual and see if you have an inside cab air filter for the heater/air cond. When they get clogged, they restrict the air flow.

Where is low port to recharge ac?


Near the firewall you have both air cond pipes coming out. There is a black cap on the larger of the two alum pipes. It is under the air filter housing and should be able to see it without removing the air filter housing. That is the low pressure side.
The high pressure should run along the chassis rail and near the radiator there is another black cap on a smaller alum pipe.
Remember always yes always vacumm the air cond system for at least 3 hours to dry out the air cond system correctly. If you don't if will only work for a short time before playing up again.
Some shops don't do this and wonder why a car keeps coming back for more gas. Good for them bad for customer.

Heater/air cond blower only works on high. any


It is the Blower Motor Resistor located behind the Glove Box on the dash. Remove the Glove box to access. It is mounted against the fire wall. This is a common problem. My 2002 did the same exact thing.
1. Disconnect the negative side of Battery.
2. Disconnected the Electrical Connection to the Resistor.
3. Remove the bolts/screws. I believe they have 8mm heads, there should be 2 of them.
4. Replace with new one.
5. Reconnect the negative side last.
6. Test System before putting the glove box back in!
7. Enjoy the CONTROLLED HEAT!!

Air cond dash light works, compressor doesn't go on.


AC's have a low freon switch that shuts off the system to protect the compressor in the advent that you have a freon leak have the system checked for a leak
