Dodge Dakota Climate Control

mstefanik1

I have read through a lot of this forum looking for a problem similar to mine - but I am not sure I have found it so I figured I would start a new one.

The blower on my 1997 Dodge Dakota has recently become intermittent. Sometimes I start the car and it works normally, sometimes I start the car and it does nothing - at any speed. I thought it might be the resistors, but as I understand the system at the highest setting it bypasses them.

There are also times when it seems to pulse, and an audible noise is emitted. A couple of times I have succeeded in cycling the system on and off enough times where it kicks on, but this is not the norm. Normally it seems to either work when I start the car, or not.

My A/C has a similar problem, but as it is winter I am less concerned about this at the moment - it's the defrost I need now!

Is it still likely the resistor assembly? Or should I look further downstream?

Sounds like possibly a bad connection. Pull the connector off the resistor and check for signs of over heating. Make sure the connection to the blower motor is ok. Check the connector at the switch. Possible broken wire--wiggle the wires to see if the motor will come on & go off.

You ever get this fixed? I have same issue

I have same paroblem, did you ever figure it out?

Actually, when the problem started was when I install a new radio. So I reinstalled the radio and re-connected all the connector on the climate control panel and it went away. I have not been able to check it the last six months, I am currently deployed, so truck has been sitting.

Thanks, I suspected the control panel. More importantly, thank you for your service!

Blower resistor costs maybe 12$ and its underneath the dash on the passengers side. Common problem

If there ever was a come on for car shoppers - here comes www.TRUECAR.com . This sleazy outfit tricks unsuspecting buyers that it is showing all of the prices for vehicle purchases in the general area - they are not. RIPOFFCAR does no such thing. Instead they do not include prices the heavy discounters sell to the public with. This has the effect of making unsuspecting carbuyers believe they are getting a good deal - but they are not. I can't believe consumer reports and other "reputable" organizations use this outfit. Don't spend a dime with Consumer Reports or any other service who use TRUECAR. Every time these sleezeballs help get a car sold, they get $300 bucks for the "lead". So if you go on USAA or american express and get a price off of their websites, instead go direct to the internet manager or use Carwoo to get a better one. I hope the CEO of TRUECAR chokes on it. By the way, I am merely offering an opinion. I believe in free speech. Thanks to Edmunds for this message site. And enjoy your new Honda Accord - what a great car.

I have a unique situation. Since the truck was brand new (I'm the 2nd owner but I know the original owner personally) all fan speeds function but the highest setting (Max with Re-circulation) is equal to low on any other car. The driver would usually require all vents just to be moderately comfortable. After researching this for a long time, I replaced the blower motor resistor. It was the original resistor and there was no evidence of heat or other damage. The blower now works on all fan speeds as it should. Very strong Max and now we can actually split the vents 2x for driver and 2x for the passenger!

Thanks for posting your solution.
