Tech 1....??

[LannyL81]

In the diagnostic for my air distribution problem, the service manual calls out using a "Tech 1" and a Body Systems Cartridge.....what are these?

Am I forced to take the car to the dealer to get this diagnosise?

Defrost is the home position for the air vents. You have a vacuum leak. Start with pulling the right side fuel rail cover and look for a "T" shaped plastic check valve. When you remove the vac lines it will fall apart. $6.00 from your dealer, $2.60 from Napa auto parts. If you still have the same problem check the vacuum control assy mounted on the fire wall up from the gas pedal. Their should be a retainer holding the vac hoses on, its more than likely gone.

Already checked the check valve...its there and working fine, holds vacuum with engine off. I have vacuum going into the HVAC programmer but none coming out on any of the other lines as I switch through the buttons on the temp controller. So either the temp controller is dead or the HVAC programmer is...just trying to figure out which.

Thanks,

If you find out I would love to know as I have the same problem with my 1996

After replacing both the control head and the HVAC Programmer with units from a salvage yard, (i.e. operational condition unknow) it appears that I have a defective HVAC Programmer. Best price for a re-man'ed one is $652! Just going to live with the way it operates for now.

You can go to my other threads and read about what all I did to troubleshoot this problem.
