A/C help
A/C help My compressor runs and my lines are doing what they are supposed to (hot and cold) but there is no cold air in the car. My fans do not come on when I turn on the a/c either.
I have 3 fan relays in the car. A high speed, low speed and a/c. I'm assuming the a/c fan relay is the 5 prong relay? I haven't heard my fans come on in a long time and my car takes a long time to get to temperature as well.
This is my first step in diagnosing the problem I guess unless anyone else has any ideas?
My temp control works when the a/c is not on. It does go from hot to cold with out the a/c.

fan only runs when temp set to hot?
or fan never runs is ur problem?
if so, give the fan direct power and check motor is ok.
if fan works, swap relays with a diff one to see if its a relay problem.

the blower motor relay is under the dash on the passenger side btw.
i have no idea what 3 relays ur talking about, but they have nothing to
do with blower motor in HVAC system.
check all ur fuses btw.

When you turn the a/c on the fan should come on to keep the condensor cool.
do u know how to check for power at relay?
do rad fans never come on?
you drive it, cars gets hot.
cooling fans never kick in?
turn on car, while someone else is in inside cycling AC on and off,
touch each fan relay and feel for a click.
if nothing= no power signal is given to turn on fans. problem is between switch and relay.
if clicks= fans are bad or broken wire. remove connectors to fan and check for power and try and power up fan direct like i said before
