What could cause a 1998 Jeep Grand Cherokee air conditioner and heater to stop blowing when you accelerate?
When you accelerate it probably does not quit blowing but rather blows out the defroster vent. This would indicate a vacumn leak or possibly a bad vacumn check valve. The check valve is located in the vacumn line that goes through the firewall somewhere between the firewall and where it connects to the engine. Check the vacumn with a vacumn guage (pump) in line going into the dash for vacumn leak. Hope this helps. Keith
