98 Dodge Grand Caravan - climate control lights flash

I have a 1998 Dodge Grand Caravan. This mornin I had a dead battery. (Yes, really dead!) I now have a new one. when I start the car, the lights on the wiper and climate control buttons flash. Buttons all work fine, as does everything else. Why are they flashing? Do I need to reset something?

Also, have continual problem with driver's side electric window. When weather gets hot, it sticks and won't drop down when button is activated. The motor and switch are working, I can hear them. Just the window won't drop. When weather cools, it works just fine. All other windows are working fine.

Any help would be VERY appreciated!

2005 Grand Caravan Will not switch air vents. I try to change to floor or even defrost and the lights indicate a change but the air never changes from blowing out the dash.

Any Ideas?

FLASHING RECIRC AND AC BUTTONS on climate control

This is a followup from reply #48

I was told I had AC evaporator leak 3 years ago and never fixed (Quoted $2000 price to pull dash and replace) Drove without AC. 2 years ago changed battery and this problem began with the climate control lights FLASHING RECIRC AND AC BUTTONS on climate control

11/7/10 with help of knowledgable friend pressure checked AC and found no obviuos leaks( held pressure 10") and used Ac sealant and recharged system FLASHING RECIRC AND AC BUTTONS on climate control continued

When I did the acutuator calibration test (Shawn#2) followed with cooldown test (Craig #42) the lights stopped flashing. Only doing the calibration test did not solve problem doing both tests in sequence fixed flashing lights

Hopefully the sealant will hold and I'll have AC after three summers without it

Hope this helps everyone

All you need to do is start your van. (if you are unsure what knob or lever is which I am looking in the manual for proper terms) Then slide your temp lever all the way to the left (full cold). Then turn the Mode Control to 'panel' (the one that sends air to your face only). Then turn the 'blower switch' to all the way to full. Now go to the leftmost three buttons. Press the top one (rear wiper on constant) and the bottom one (rear wiper washer fluid). Hold these two for a few seconds. Once the lights come on solid then begin to flash you can let go. The AC will now calibrate. You will feel the air blow out of all the different zones at different intervals and see lights come on and go off. Then after a minute or two the top bottn you pressed will be slowly flashing. This means it has been completed (I actually let it run for 5 more minutes just in case something else started blinking). Press the last flashing button and you are done.

Thanks everyone.

My 1998 Dodge GC had both the Circlator Light and A/C Light flashing.

The #2 fix 'seemed' to work until the final blinking light - the top left Constant Wiper button - was pressed to end the sequence - which turned the original two blinking lights back on.

After repeating #2, and then completing the cool down test #42, (pushing the A/C bottom right and bottom left Rear Washer buttons in unison) - all blinking lights went out by themselves.

Thanks again.

I'm having the same flashing AC and Recirculation light problem, going to try and disconnect the negative battery cable tomorrow / today actually for 5 minutes and then reconnect. Plus also does anyone see a connection to this other problem I'm having with the van dying at idle or stop but running fine at acceleration speeds on the highway?

ran Alex's test 50 sequence and it worked; 1)ran the #2 fix twice (after the first sequence pressed the last flashing button and the recirc and AC light flash again so started over; when the 2nd sequences ended pressed the blinking light and the AC and recirc light flashed) 2)pressed bototom left button and AC and waited till lights went solid then let go and it ran through another sequence and rcirc and ac lights stopped flashing.

I have a '98 Dodge Caravan and the heat just stopped working on it. Or maybe I should say the A/C won't turn off. It was working fine yesterday, then I disconnected the battery to replace the little corrosion pad under the terminal and now the A/C won't turn off. I can change the different settings from defrost to panel, etc., but it just blows cold air. Any ideas??

The lites that lite up the heater/air conditioning controls do not illuminate. Do I have to replace the complete control unit or is there someway to replace the bulbs. This is on a 2006 Dodge Grand Caravan.

Battery on 1998 Dodge caravan sport was disconnected for a repair. After the repair was completed and battery reconnected, the air vent door makes a "knocking" noise when the ignition is turned on. All vents are working correctly as does the speed control. Is this a memory problem and can it be reset, either by disconnecting and then reconnecting battery or some other way?

I did the #2 fix and the top two lights have stopped blinking. Thank you.

However I tried the cool down test #42, but the lights still blink and my a/c still does not blow out cool air.

Any suggestions?

Am having a problem with my 98 dodge caravan. Had clock spring replaced last year. Blinking wiper and ac lights, horn honked every time i made a left turn, no cruise control. the whole gambit of messed up. Now all of a sudden the light started blinking again a few weeks ago. the back wiper started wiping all by its self and had to remove the wiper arm to keep the window from being ruined. Then the ac came on by itself and wouldn't turn off. disconnected it. As soon as we did that the transmission stopped working. Is everything on this van dependent on everything else!! About to lose our minds. Can't afford a new car right now.

Hi,

I have a dodge caravan 1998, and about 1 year ago my battery went completely dead. I brought a new battery and had it installed that is when the climate control light started blinking. My machanic told me that once the battery was reconized the blinking light would stop.

I did the test on #2 and it recalibrated the a/c and did exactly want was noted in #2 but the lights kept flashing. Does this mean i have to replace the whole climate control module.
