This can result from heater core blockage. If it is partialy blocked, you may notice a little heat with the fan on low, but it goes cool when the fan speed is increased. Other signs of blockage may include engine temperature fluctuation, and/or excessive pinging (pre-ignition). This can also be caused by the engine thermostat being stuck in the open position. Cracked heater core.
I had this problem before on a ranger you have to pull the dash board out and it will be right there.
Weak fuel pump
Check the part numbers at a rad. shop.
low coolant? Bad thermostat? heater core airbound? control cable not adjusted properly?
took me about 2 days, you have to remove the dash completely to get the heater core out. I suggest paying to have it done. I sure will if it ever happens again
It is either the fuse or relay. also check the heater/ ac control switch.
Probably. As a mechanic, I would attempt it.
You have to remove the dash and cowling underhood to remove the heater case. Then you would need to disassemble the heater case.
your power control module is under the hood on the passengers side on the firewall right above the heater core hoses
hi, i need to know how to replace the heater core with a/c on a 1994 gmc jimmy. a diagram would be helpful
On my 1994 Ranger, the heater core is directly underneath the glove box. All you do is crawl underneath the glove box, losen 4 screws in plastic housing, and pull the housing off. Make sure to losen to hoses underneath the hood located on the firewall to drain the antifreeze. Once this is done pull out the heater core. Mine was fairly easy and took under an hour. I hope this helps somebody. 1993 and 1994 Ford Rangers have the easy out Heater core anything after you have to take the entire console out with the dash.
