Question about 1999 Jeep Grand Cherokee

1 Answer

Heater blows air just a little heat

I have a 98 Grand Cherokee, 5.9 Limited. The heater/AC blows with a little heat, not like it used to. I used to be able to set the climate control on high and it would sweat you out of the car. Hubby is a mechanic on heavy equipment so he has checked all that he can think of. Not sure if the A/C is blowing normal or not, it's been 10 degrees outside. Thought I would come to the internet for some help. Any ideas would be greatly appreciated!

Start with the basics... Is there plenty of coolant in the system. Many people including myself have overlooked the obvious. THEN...
You may need a GOOD new thermostat. I had the same problem twice on my first generation Dakota. The problem for me turned out to be the DODGE thermostat I used to replace the old Dodge part. I went and got a Stant brand from local auto parts store using the standard temperature spec and quit shivering the next time I drove it. I don't know if your engine is a Dodge or Chrysler engine, but it sounds like the same thing. I guess when the thermostat gets old it opens up too soon and prevents the engine from running at the corect temperature. You may get better gas mileage and performance out of the deal as well.

How do i replace/install a heater core for a 1999 limited edition jeep cherokee 4.0 liter 6cyclinder


I would make sure the core is the problem. You may have a heater control valve that cuts off flow to the core by vac. or a blend door that cuts off air flow thru the core.
You will need a shop manual to replace the core. The dash and console have to come out, along with discharging the ac.

The control for the AC/Heater door isn't working. To have AC the door has to close so that the hot air is not being blown into the car. When this door is closed it allows the cool air to pass through. This is either controled by vacuum or a ele. switch

2001 Grand Cherokee Heat on one side cold air on the other side?


The blend door on the passenger side has broken. Jeep has made a replacement section for the heater box assembly so you don't have to buy the whole thing. You will need to remove the heater/A/C box to replace the part. I have done quite a few of these repairs to fix the problem

Heat


Mine did the same thing. The quick fix is to turn the knob to the heat side, then push gently on the knob itself. You'll instantly feel the air get warmer. The real fix entails taking the dash apart.
