(1) In summer, when the weather is hot, air conditioning system in automatic control mode, when the temperature is adjusted to a lower temperature value, the cold wind will not bring out instead of hot wind, and air conditioning system control go to trouble mode or protected mode, the cold / warm mixing stay in the position of hot wind.
(2) In winter, when the weather is cold, air conditioning system has no warm wind, t the cold / warm mixing is locked in the position of cold wind.
Possible Reasons:
The air conditioner cold / warm wind door shaft has manufacturing deviation and the software of air conditioning module has poor suitability, the specific reason as follows:
There are two reasons why it has hot wind when the weather is hot:
(1)possible reason one: the C8 pin of air conditioner control module shows signal there is no electronic currency, after the system set trouble codes, the controlling software become fault mode, and command cold / warm mixing wind door stay in the position where blow hot wind. The main reason is there is no electronic currency in the air conditioner circuit or the sliding resistor in the cold / warm wind door electronic motor; besides, cold / warm wind door shaft has hardware production deviation which may cause voltage higher than 4.98V in the process of adjusting and cause the trouble, but at this time, air conditioner system doesn’t set trouble code, because when the air conditioner control module send out command requesting the temperature adjust to the highest, then the voltage is also the highest, at this time air conditioner system is supposed to blow hot wind.
(2) possible reason two: the C8 pin of air conditioner control module feedback the minimum voltage less than 0.35V but not less than 002 V, at this time air conditioner control module doesn’t set trouble codes, the control software go to protected mode, with the rise of automatic control temperature, protected mode will cancel automatically, then in automatic control mode, air conditioner system will produce hot wind not cold wind when the temperature is set to a lower value. But when the temperature is set to a higher value, the control system can work and the manual control mode can work either.
(3) In cold weather it doesn’t blow warm wind, possible reason: When air conditioner control system in automatic control mode, cold / warm wind door electronic motor show voltage signal ground short circuit or voltage value lower than 0.02V, at this time the control software go to trouble mode and set trouble code B0361 (cold / warm wind door is locked in the position of cold), and both the manual mode and automatic mode of air conditioner control module fail to control, only to disconnect power supply can trouble mode be canceled (Note: if it fail to recover, please instantly connect C1 and C7 port)
(2)Improper operation: in short time, the car owner repeatedly press or choose the function buttons on the air conditioner control panel, which cause a disorder of the control module because air conditioner control module receive many other new command before the previous command hasn’t complete execution.
The way to test:
(1) Firstly, connect GM Tech2 scanner(I ordered from www.obdii365.com ) with Buick Regal, and read out current or history trouble codes for air conditioner control module.
(2) Then measure the voltage of air conditioner control module C8 pin, which help the repairman analyze the specific reason. When air conditioner control module in manual mode, C8 pin ideal voltage is 1-4V, if the tested voltage less than 0.35V at minimum, then the control module is likely to disorder, if the voltage is less than 0.02V, then the control module will definitely disorder.
4. Possible solutions:
(1) Under various conditions, if the voltage of air conditioner control module C8pin is not less than 0.35V, please refer to the trouble code information and the user manual to check the circuit or sliding resistor in the cold / warm wind door electronic motor, if there is any fault, troubleshoot it.
(2) Under various conditions, if the voltage of air conditioner control module C8pin is less than 0.35V, then the possible reason is that cold / warm wind door shaft has manufacturing deviation，there are two solutions to solve the problems.
A. Change the air conditioning container body assembly (or change the cold / warm wind door shaft.
B. Adjust the relative position of the sliding resistors passive gear in the cold / warm wind temperature actuator electronic motor, and make C8 pin Voltage in an idea status. Please attention: only the old cold / warm wind temperature actuator can adjust feedback resistor gear, but the new one can’t do.

GM Tech2 TIS2000 Not Run XP Mode On Win7
One of obdii365 client bought the GM Tech2 Scanner and the GM TIS2000 software CD , he message to our customer service that the GM TIS2000 software did not Run In xp Mode On Win7.
Problem:
"I use a Tech II diagnostic tool or a gm MDI to attach it to the truck, its on a cd / dvd, its a program i got on-line to reprogram GM BCMS in my truck. my problem is I can load 2007 software [its called ”TIS2000] into my computer [it only runs on a ”win xp” machine”][yes it won’t run in xp mode on a win7 machine],but I need the update to 3/2008 or 8/2008,to get it to see my vin#, so I can add power adj pedals[and some other options, I can’t get the 3/2008 to load. ”
Obdii365.com Engineers Solution:
Depending on your computer hardware, you could install XP and your app in a Virtual Machine (VM) from Windows 7. Once installed and configured, you would boot your computer like normal and start XP in a window.
VMware makes Virtual Machine software called Workstation v10. They have a trial, but expect money at some point. The second best option for VM software is called VirtualBox from Sun. It is free!
You would just need a compatible computer, a copy of Windows XP and time to learn the ropes and get your XP Virtual Machine (VM) up and running. Learning how to use it is a one-time thing and at that point you’ll be familiar with VM software in general. That is a huge benefit to have as a computer user.
At that point you would meet the requirements of the GM Tech 2 software and would install TIS2000 within the VM and use the virtual com/serial port to connect to your computer serial port (or USB).
