Question about 1999 Jeep Grand Cherokee
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.
