2001 Chevy 1/2 express van.A vacuum line under
The vacuum line from the engine's intake manifold goes to a vacuum reservoir ball under the hood; from there a vacuum line leaves this reservoir, passes through the firewall and connects to the mode control switch.
The mode switch directs vacuum to actuators that position the doors to the desired vents. When there is no vacuum the doors are pulled by springs to a rest position; defaulting back to defrost.
The vacuum reservoir is used to store vacuum when the engine is under load and not producing large amounts of vacuum. The inlet vacuum line may have a check valve; stopping vacuum from going back to the engine. Make sure that this valve (if there) will only allow vacuum to pass through it in one direction.
The lines that control the AC and heater all pass through the firewall and some are up around where the wipers are if there are no lines coming out of the firewall except the one by the brake booster then simply plug the line coming off the T with a screw and see if that restores your vacuum to the controls. You may just be leaking so much your controls arent working. These lines that run around the manifold tend to disenegrate over time and with out seeing the issue I have to guess that the one unconnected line is either broken off and should connect to something withing its length or the hose itself could be cracked in half which leaves the other half hanging out there somewhere.
You might need to remove the center console & the engine cover in order to access the main vaccum line that is right in front of the PCV valve on the driver's side of the engine. Make sure you have a really long flat head screw driver to remove the two slotted bolts on the engine cover on the firewall. Also, since the placement of the vacuum hose is definitely a design flaw as it cannot stand up to the heat of the engine for more than a few years without degrading the line, make sure you invest in a heat shield wrap or another larger vacuum hose to engulf the replacement hose & to act as a heat shield. I recommend replacing all of your AC vacuum hoses at the same time
When i press the ac button it blinks three times
If your vehicle is equipped with automatic climate control, this should help.
The HVAC control module controls the air intake through the recirculation actuator. The recirculation switch closes the recirculation door in order to circulate the air within the vehicle. The outside air switch opens the recirculation door in order to route outside air into the vehicle. Regardless of the blower motor switch position, recirculation is available only in the panel and bi-level mode switch positions. Including the OFF position. The mode switch must be placed in either the panel or bi-level position before the blower motor switch is placed in the OFF position. In order to reduce windshield fogging, outside air is circulated when the mode switch is in the defrost or defog positions. If the recirculation switch is pressed into the ON position when the mode switch is in an unavailable mode position, then the recirculation switch LED will flash 3 times. If the HVAC control module detects a fault with the recirc door the HVAC control module will try to drive the actuator for a predetermined amount of time, to outside air, which is the defaulted position for the recirculation actuator

Where is the location of the fuel filter on Chevrolet Cruze
The fuel filter on the Cruze is underneath the car on the passenger side. To access it:
• Remove the aerodynamic housing
• Keeep an oil pan underneath to catch the residual fuel
• Use a wrench to open up the filter, and once you see the O ring, start unwinding by hand
• A housing will drop out with the fuel filter-put some pressure, and you can remove the fuel filter.

Just repaired code 136 on a 2013 chevy Orlando and it was a detached ground wire on one of the starter bolts causing the fusebox relays not to energise.

Have a u1041 loose of ebcm ebtcm communication code on 2001 cherolet tahoe
A U1041 code means that communications with the electronic brake control module are lost, and this may have happened because:
• Electronic Brake Control Module harness is open or shorted
• Faulty Electronic Brake Control Module (EBCM)
• Electronic Brake Control Module circuit poor electrical connection
To fix the issue, inspect the issues mentioned above and check that all the wirings and connectors are intact-nothing should be broken or corroded.

Chevy Malibu power adjustable driver's seat stuck
If the seat is not moving forward or backward, but you do hear a click or a motorsound- chances are that you dropped in some change or other debris may be blockling the way. You might also have blown a fuse - look for fuse no. 30, which is a 30 Amp fuse.
Once you've checked all that and if the motor still does not run, then the problem may be with your wiring.
Wire colors between the switch panel and motor are:
• Fore/aft-Tan and Lt Green
• Front up/down-Dark Green and Dark Blue
• Rear up/down-Yellow and Light Blue
• Recline up/down motor's Blue and Light Green
