first gen tundra A/C

my truck doesnt blow cold and AC button flashes i know im not getting any voltage to my compressor... but when i jump it with 12V it enages... i checked my freon levels and there sitting around 120 obviously without the AC running but i tried jumping my high low sensor but still nothing and i tried bypassing the heater relay and nothing. I know my ambient air sensors are well grounded. One thing I did notice was a gray wire going close to that connection for the compressor i think its a bypass but it gets low voltage...

 

Try replacing the ac relay with OEM only. I think some first gen’s use the heater relay but others have a separate one.

 

Have you tried the 1st Gen forum?

 

Make sure also the ground wire on the compressor is not loose
