I recently charged my ac unit on my 2006 f150 5.4. It is not blowing cold air. The compressor switches on for about 5 to 10 seconds, then switches back off, it continues to switch on and off. Hit 100 degrees today, no ac. Any advice or tips?

 

Feel the low pressure side of the system under the hood by the firewall. Is it getting cold? It could be an airflow problem.

 

Ok will try tommorow morning. Thanks

 

also check to see if there is too much freon in the system. The compressor could also be wearing out and needing a washer removed off the clutch so that the magnets engage properly again. Look up the procedure on youtube.
