2000 CARAVAN WONT START AFTER DASH REMOVAL TO REPLACE EVAPORATOR CORE. After put everything back on and tried to start it, the only thing i get is clicking noises from under the dash and under the hood and humbling noise from the box under lower heater duct, sometimes the odometer and shifts acreens are going blank or the speedometer needle jump to 45 mph, i operated the keyless entry by mistake and everithing was acting like crazy ( doors locks, gages ) for about a minute, and sometimes when turn the switch to start position i dont have nothing, no clicking, no screens, no gages movements. the battery's negative cable was disconected during the whole removal procedure, everything was working perfect before besides the leaking evaporator core, any help would be greatly aprecciated, thanks.

In my experience with problems similar to this, when nothing makes any sense at all, it has most often been a ground that was left off or pulled loose by accident.

some times you can find these by getting a jumper wire and grounding one end, and touching the other end to the wiring harness ground points.

A ground is common to many electrical components under the dash. this is why a loose ground could affect so many different things at the same time.

Hope this helps

Our front ac is not working and back is cold in our 1999 GMC suburban, we tried putting freon and it didn't work

Dual zone front/rear ac systems have 2 evaporator cores. And 2 orifice tubes, which are just inline
filters. Either your front evaporator core or orifice tube is probably stopped up.

Sometimes you can get to the evaporator cores without removing them from the vehicle, and clean it.
Evaporator cores do get stopped up sometimes, because the blower motor pulls in air with dust and debris from outside, and the air is cooled when it passes through the evaporator core.

But evaporator cores are a nightmare to replace, you usually have to remove lots of stuff under the dash and lots of stuff under the hood to remove them.

I need to know how to remove the evaporator coil on a 2000 dodge grand caravan. i have already removed the dash and all the duct work but i dont see how to get the box out that contains the heater core and...

Woo hoo i finally did it. To remove the a/c-heater housing unit you have to remove the dash, the duct work, and all the metal framework behind the dash.Its a lot of parts and it takes time but its doable. Just be careful and make sure you pay attention or label everything. Once you get the housing unit out, its cake from there. Just take all the screws surrounding the blower motor and then it will reveal more screws. So continue to take screws out and the top will come off. Then there it is, remove the evaporator coil and remove the expansion valve and place on the new evap coil and installation is reverse of removal. Thanks for help and this is cool I solved my own problem.

You will need to remove the entire dash assembly to replace the evaporator core, unless you have a really good understanding about such work I would leave it to a professional, if you still want to do the job yourself post any questions you have about removal of the dash and I will try to help as much as possible.
