Changed ac condenser and heater coil on my 2011 Dodge ram 2500 hemi. Put it back together and now abs light , emergency brake light is on and speedometer and cruise control doesn't work. Anyone have any suggestions on where to start looking for the problem?

 

Don't the newer trucks use a wheel speed sensor on one of the front wheels for those functions? Check and see if either side has the sensor, and make sure they are still plugged in.... If you have 4 wheel abs, both sides will have a sensor.

 

Will check thanks

 

Have you figured out what was causing the issue? I’m never changed anything with the ac but I am having the same issue and have for years. ABS light, emergency brake light and no cruise control

 

Go back to basic, Problem started after you replace the heater core and A/C evaporator. Which means you pulled the dash? I would check the connectors under the dash first.

 

I have pulled the dash about 1000 times lol. For many different reasons. Everything is plugged up as it should be tho i believe. This problem has gone on for 3+ years and ive pulled the dash many times and the lights have always been on

 

Cruise control could be a clockspring, could throw a traction control or ABS code. Does the horn work when you push down on it?

 

The "emergency brake light" is also the light if the brake fluid level is low. It's not only to notify when the parking brake is set.

It's possible that you have at least two issues here, one relate to the Brake light in the dash and one for the ABS, which could also be the reason the cruise control doesn't work. It's not uncommon for the cruise control to get it's vehicle speed input from the ABS system. If you can get access to a scan tool that can pull ABS systems diagnostic codes that might give you a great head start on where to start looking.
