How to remove dash in 1997 venture?

If the dash has to come out then it has to come out.

This van uses a power operated air temperature control blend door inside the air ducting, if the electric actuator that moves the door is defective or the door gets stuck (both are common) then you either get stuck with hot air or cold air all the time, that is likely your problem. To replace the blend door requires the venture dash be removed. Please have this confirmed by the dealer before you remove the dash which is a 12-14 hour job for an amateur

The fact that its blowing cold on one side means that the AC system is working correctly . However the air flow is controled by vacuum actuators inside the the dash board . There controled by engine vacuum and open and close little dors inside the duct work that roots the air into the cabin . Unfortinatly there not always that easy to get to with out removeing the the dash .Look up under the dask try to follow the duck work it may be just stuck or a disconnected hose or a split hose But your AC system is working and this is where the problem is . Good luck with it

go under right side dash and look for an acsees panel on the evaporator case with one screw in it 5.5 mm remove your clogged clean air filter if that doesnt fix it the evaporator core is clogged with dirt and debrie.but the clean air fitler should fix your problem

The cabin air filter is usually located behind the glove box or at the base of the windshield in the cowl area over the HVAC inlet duct. The exact location can be found in the vehicle owner’s manual or a filter reference guide at the auto part store where you purchase the cabin air filter from.
On most Fords, the filter is located under the hood in the cowl area. On Chrysler models, it is located under the dash. On GM products, it might be under the hood (Impala, Lumina and Monte Carlo), under the dash (Avalanche, Silverado, Suburban and Tahoe) or behind the glove box (Venture). On Toyota, Lexus, Nissan and most Honda models, you’ll find the filter behind the glove box. There is no cabin air filter even listed for a 1998 Oldsmobile Regency.

On vehicles where the cabin air filter is mounted under the cowl at the base of the windshield, some disassembly may be required to replace the filter. This may involve removing a plastic cowl cover. The area around the filter usually collects debris, so this area should be cleaned to remove any leaves, bugs or other debris before the old filter is pulled out. This will prevent any contaminants from falling into the HVAC inlet duct.

On vehicles where the filter is located behind the glove box, the glove box may have to be removed to replace the filter. On others, the filter can be accessed from under the dash and pulled out of a slot in the HVAC unit.

Most cabin air filters are flat-panel filters, but some have unusual shapes, so they will fit the HVAC inlet duct. Some filters also come in two sections to make replacement easier.

   NOTE Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
